Race to the Finish

Race to the Finish is a recurring 1-player mode that appears in both Calssic Mode and Adventure Mode in Super Smash Flash (but currently unconfirmed for Super Smash Flash 2). The main objective is to cross and get past through obstacles to reach the end before time runs out.

In Super Smash Flash
Race to the Finish is the sixth level of both Classic and Adventur Mode. Players must cross through a longer version of Emerald Hill Zone, with small platforms scattered between two big platforms, the one on the far right being where the finish line is located. There are also Buzzers, robotic-bee enemies from Sonic the Hedgehog 2, that float toward players to harm them and block their jumps, fortuneately, they can be easily beated in one attack. There two variations of the extended Emerald Hill Zone, the one in the Classic Mode is a bit easier as it follows a straighter path, while the one in Adventure Mode represents more a challange as it follows a right-diagonal path that forces the player to make more precise their jumps.

In Super Smash Flash 2
Nothing is confirmed about how Race to the Finish will work in SSF2, or even if this game mode is going to be in the game at all.
