really cool game, it's fun to play, and great idea! there are a few minor bugs i found(if a player is standing on a white trigger and the other player steps off, the game thinks there are no players on it), but nothing too big to destroy the game. the levels are also very hard in platforming skill, which may cause people to not want to play it. i really like the sound of players dying, i could jump into a red square for hours and just listen to the sound.
overall, great game with great potential, i could imagine this as a game you would play on coolmathgames(it's a compliment btw) while having class.
