List of bugs and glitches in Super Smash Flash

A glitch is a common term for any behaviors or interactions in a video game that are not intended by the developers. They are usually caused by programming errors within the game's coding.

There are many different kinds of glitches, as they can appear almost anywhere within the code. Some glitches will crash the game or otherwise render it unplayable, while others are relatively harmless, or even enhance the game. Some glitches are caused by damaged games. Some only activate when the player presses a certain sequence of input commands (pressing buttons). Other glitches can actually create new levels occasionally made randomly and haphazardly, and others allow players to guide their character off-screen, sometimes granting them access to other glitch-like areas (usually composed of many garbled symbols) and even unused parts of stages.

Glitches in Super Smash Flash
Since Super Smash Flash was coded by an inexperienced Cleod9 as his first major project, it is not the most stable Flash game out there. Below is a list of some notable glitches in the original Super Smash Flash.

Damage input flaw
This is technically not a glitch but rather a game flaw that leads to several unintended behaviours that are worth noticing. Because the game's method for determining damage calculations is broken on a fundamental level, when an attack makes contact with the opponent, rather than apply the damage for an attack once, it applies the damage on every frame that the move's hitbox is overlapping the opponent's hurtbox. This results in attacks that deal ludicrous amounts of damage across the board, with some moves being capable of dealing over 100% in a single attack.

Instant-kill attack glitch
The most infamous glitch in Super Smash Flash, being so prevalent and unavoidable that it has become synonymous with SSF 's physics. Every character has at least one attack (normally the up attack) that will, on contact with a moving player at around 50%, cause them to shoot sideways at a high velocity, causing them to die almost instantly. Combined with the damage input flaw above, all matches in SSF tend to be over in a matter of seconds. As a result of its prevalence, it almost single-handedly defines the metagame; the most important trait for determining character viability is based on how easy it is to get an instant-kill attack off on their opponent.

Master Hand and Crazy Hand are not exempt from this glitch, having a number of instant-kill attacks themselves, including a pushing move that sends the player straight up. Because of this, unlocking proves to be incredibly difficult without use of the skip glitch or the easy avoidable Hands glitch below, as failure to dodge even a single attack can lead to the loss of a stock.

Skip glitch
One of the more popular glitches in Super Smash Flash due to the beneficial results it can be exploited for but also for other curiosities. It can be used in Classic mode, Adventure mode and All-Star mode. The glitch has two methods of executing: one by opening the right-click menu and selecting "play", and the other by pressing Ctrl along with an arrow key. If forward is clicked or Ctrl+Right is pressed while in any of these game modes, the computer will be tricked into passing the player to the next level, as each game screen is essentially treated as its own "movie"; contrarily, clicking rewind or Ctrl+Left forces the player to replay the previous level. This glitch is unable to function properly in the Target Test, however, as not only does it not advance the player to the next level, it restarts the level with another fighter's target layout in a fixed order, forcing unusual and occasionally impossible situations. This is notable with, who is sent into 's layout, which has a target that is inaccessible without his boulders. When performed by, the last character ID in the roster, the game will go back to the Target Test character select, aborting Classic mode.

This also leads to another glitch called the night glitch (see below). The following glitches involve the skip glitch:

Night glitch
This glitch can only be found in Target Test. To exploit this glitch, the player has to finish the character(s)'s target test; immediately after the announcer says "Complete!" or "New Record!", the player must use the skip glitch. This will restart the level in a purple tone, dubbed fittingly the "night glitch." This glitch is often accidentally triggered when players, impatient with the results screen, blithely clicks Ctrl+Right/Forward and finds themselves stuck in Target Test yet again with a differently-colored background.

Cloud's fast-unlock method glitch
The skip glitch can also be exploited to challenge and unlock instead of the intended method of completing 100-Man Melee. The player has to unlock Burly Brawl Melee and set a match with any character; once the match has begun, the player must use the skip glitch method and the Multi-Man Melee will be completely skipped, leaving with the Challenger Approaching! screen for Cloud, where victory will unlock him. This glitch can be repeated over and over, even with Cloud himself, and the notice that reads he has been unlocked will also be shown again upon defeating him, said notice will also be recorded again in the Special section on Data.

Crono's rematch glitch
Using the skip glitch once more during Cloud's unlock match or during the notice that reads Cloud has been unlocked unlocked, the player will be taken to the Challenger Approaching! screen for, allowing a "rematch". This glitch is certainly less useful than the glitch described above as Crono is supposed to already be available, because he is unlocked alongside Burly Brawl Melee, the mode required to exploit the glitch. As with Cloud's method, it can be repeated over and over with any character, even Crono, and the notice will also be recorded again on the Special section on Data.

Blank menu glitch
Attempting the skip glitch during Crono's match or the notice screen, it will take the player to an empty menu screen with a unusable Back button. To solve this, either closing the window or, preferably, using the skip glitch again, which will take the player to the character select screen for Training mode and everything will go back to normal, albeit with themes of Final Destination and the Menu music overlapping each other.

Null character glitch
If the skip glitch is used on a character selection screen without choosing a character first, an empty character will be chosen with no sprites and no collisions. This character will fall through the stage and die immediately.

If this is done on Target Test, the null character will fall infinitely, showing a permanently white screen, because Kirby's Hub Room has no blast line programmed.

Note that this will only happen in situations where the game expects there to always be a character, such as when the null character is player 1. Attempting in Training mode or Melee mode with any player other than 1 while player 1 does have a character chosen will simply create a one-person match. In the case of the latter, a stock match will end instantly, assuming the only player to be the last one standing and, therefore, the winner.

Empty All-Star glitch
If the skip glitch is used in the All-Star mode, the current opponent will be taken out of the rotation as if they were defeated, but the game will not advance the player's progress in the mode. This leaves a gap in the lineup, which is filled by an extra at the end. The more times a player uses this glitch, the more times they will have to fight Mr. Game & Watch. If all characters are eliminated in this way, a single Mr. Game & Watch will be fought repeatedly, even as the mode advances to where two or three opponents are supposed to appear; the remaining opponent slots are occupied with null characters.

Easy avoidable Hands glitch
There is a glitch while fighting Master Hand and/or Crazy Hand that facilitates facing these bosses; when they attack the player and then it pauses the match, both Hands' animation attack will continue but the player will not take any damage. This can be exploited by repeatedly pausing the instant the Hands strike.

Early accessible Final Destination glitch
Only found in the EXE version. For unknown reasons the supposed unlockable stage is available for Melee and Training mode when the player unlocks. This glitch is not present in the Newgrounds version, however, and disappears once the player close the game.

Sudden stopped item glitch
If a player throws an item and pauses the game, the item will make an abrupt stop in place only to resume its way once the game is unpaused. If the item is thrown is midair, it will slowly descend in a straight line until it touches the floor or disappears on-screen. A thrown Bob-omb will immediately explode upon contact with the floor after pausing and will fail to deal any damage and knockback should there was a player in its proximity, unless the game is unpaused right during the quick explosion animation.

Screwy items glitch
This glitch is only possible in Training mode as it requires the player to pick any kind of item and then generate a countless amount of items of the same kind until they flash, this is noticeable when a glitchy rectangle is visible around the frame of the generated pile of items. Regardless of the item, after throwing it, the player will be unable attack at all afterwards, except for the down attack, as the game still thinks that the character is holding item; in order to being able to attack again the character must be KO'ed. The effects after throwing the grabbed item are the following:


 * Saber: Every time the player presses attack, the character hits itself with the Saber and gains damage.
 * Bob-omb: The character gets hit by multiple explosions that deal up to 600% of damage and will usually get instantly KO'd unless the player can react fast enough to stop the launch. Pressing attack again will do nothing.
 * Fan: Every time the player presses attack, the character hits itself with the fan and gains damage.
 * Flipper: The character can throw the Flipper over and over again by pressing attack continuously. If the character is using a Flipper, it follows the player's eyesight and the player can move the flipper by moving the character.
 * Fire Flower: Every time the player presses attack, the character flames itself and gains damage.
 * Green Shell: The character can throw shells over and over again by pressing attack continuously. If the character is using a shell, it follows the player eyesight and the player can move the shell by moving the character. Also, every time the character uses a shell, the character hits itself and takes damage.
 * Heart Container: The character can hold and use it, but it will have no effect. If a CPU player runs into it, it will use the item and recover health. After that, the character cannot attack except for the down attack.
 * Home-Run Bat: Every time the player presses attack, the character hits itself with the Home-Run Bat and gains damage.
 * Maxim Tomato: The character can hold and use it, but it will have no effect. If a CPU player runs into it, it will use the item and recover damage.
 * Motion-Sensor Bomb: It follows the player eyesight and the player can move the bomb by moving the character. It will fly in an exact straight horizontal line.

Mega explosive damage glitch
This glitch works in Training mode with either an explosive item, Bob-omb or Motion-Sensor Bomb. With the case of Bob-omb, the first player should run setting at the same time many Bob-ombs in chain as possible around the CPU second player living a large part with more bombs. The CPU player should be located a part of the bomb chain so a thrown bomb will not touch its and hurt its, then the other player must grab a bomb and throw it, as said before, without hitting the other player. With the case of Motion-Sensor Bomb, create countless these bombs. Throw all of them together at the same spot. Do not move until the character have thrown all of the bombs. Then, set the training mode opponent to human. Move its or the player's character to the bombs. If the player or the opponent survived, the player will not be able to use any moves at all. In both cases the bombs will explode in chain dealing a damage to the CPU player or the same player of more than 1000% but offering no knockback. Any hit will KO the player.

Suspended automatic items glitch
Only possible in Training mode, the player has to generate as many Bob-ombs as possible then attack them with a battering-type item, like the Saber or the Home-Run Bat. If done correctly, the Bob-ombs will explode and the item the player attacked with will be suspended in midair, rendered unusable. Pausing and unpausing will cause the item to "come back to life" on its own and will automatically charge a Smash attack, if the opponent is located to the proximity of the item, he/she will get attacked by it. This process can be repeated several times by pausing and unpausing until the item disappears.

Newgrounds leftover glitch
Only found in the EXE version. By stretching the size of the window widely in the game's title screen, the Newgrounds logo mark that appears in the Newgrounds version of Super Smash Flash will be visible; this mark could be also clicked leading to the Newgrounds homepage. Why this was left is unknown, but it could be merely an oversight of Cleod9 and is merely a leftover of the game, as the Newgrounds version was released first before the EXE version.

Going-through glitch
In Adventure mode's first level, Super Mario World, there are some odd collision detection behaviors on the plateaus and warp pipe found on the stage. If attacked and launched far enough by an enemy, the character will pass through the solid parts, ignoring the collision detection, and get inside the plateaus and warp pipes. The character can get out by merely walking out the direction they were launched in, but there are chances he/she might get stuck in the area, forcing the player to quit.

Do not post glitches here until the final version of the game has come out.
