This version of the game was only given to the people who backed the game originally on Kickstarter. This version of the game is so...interesting. For pete's sake Lilac is a HEDGEHOG in this version of the game. Also, the boost works really weird in this version of the game, you kinda jump up automatically whenever you use it, which makes some areas kinda difficult/annoying. It also launches you all over the place sometimes. Oh yeah, and freaking SONIC MONITORS instead of those crystal clusters in the full game.
