Really good but...
Well as everyone is saying its a bit buggy and slow, the Keys and Gravity Changers are very Presice to hit. its still a good addition to the Shift Series but its not quite there yet. also an addition that'll be missed is the LEVEL EDITOR! now i dont know if i speak for all shift players, but who doesnt have fun with tiddling around in the level editor to make an awesome level and then showing it off to your friends? and one more thing, whats with the pixely animations? im guessing the original Alt-Shift was made a while ago and that'd explain the Pixels and no level editor, but im sure EVERYONE will be happy if you could edit this a bit and add a level editor!
