Rainbow Route

Mirror Chamber (formerly titled Rainbow Route), is a starter stage in Super Smash Flash 2 based on the primary location from the game, Kirby & the Amazing Mirror. It is very similar is terms of appearances to Super Smash Flash ' s Kirby's Hub Room.

Layout
Rainbow Route once again appears in Super Smash Flash 2, but this time as a full-fledged stage. Due to the large number of platforms and walking space, this stage can be very difficult to play on. For example, most projectiles will not work well in this stage. The main focus on this stage appears to be the blue platform in the middle below the golden mirror that served as the entrance to the Mirror World in Kirby & the Amazing Mirror. It regularly opens and closes.

It should be noted that for its appearance in Super Smash Flash 2, Rainbow Route once again uses its original tiles, albeit revamped this time.

Music
This stage's BGM is a remix of "Nature Area" from Kirby and the Amazing Mirror arranged by BlueComet.

Origin
Rainbow Route is located at the heart of the Mirror World. It connects to each of the levels that Kirby must enter to find the Mirror Shards. It begins as a simple grassland, but the scenery changes depending on where it's located, such as having a mountainous terrain when approaching Mustard Mountain, and pine forests surrounding Carrot Castle. Being the first level, the earlier parts of Rainbow Route do not have many challenges and is overall easy to venture through. As Kirby's quest progresses further, he moves to harder and more diverse parts of Rainbow Route, which have more complex puzzles and a wider array of enemies and impediments. The only place Rainbow Route does not come in direct contact with is the final level, Candy Constellation. SSF and SSF2 appearance is directly taken or based on the starter chamber where the Mirror Shards are placed and Kirby can access to other locations via special mirror doors.

Rainbow Route is also the place where Kirby first meets with his Mirror World counterpart, Shadow Kirby.

Tournament legality
Mirror Chamber was originally seen as an excellent starter stage when hazards were turned off. However, as more characters with long or disjointed range were added, the stage started to become more in favor of these types of characters. The floating platform in the center gives anyone who is underneath it complete control over the stage. This allows characters with long range to limit an opponent's options and punish any move they make. Another reason was the stage was viewed as large and the small blast lines helped in getting the stage banned.
