Just played it. What a damn good game.
Highly suggest checking it out if you're looking at the comments to see what people think of it.
I like that "New puzzle" idea, it'd add some variety. Besides, as the levels go up you're supposed to be better at that thing. Might as well represent that in-game.
Horrible comment. Stop making comments, okay?
Man, this train really has a bad opinion on Bikes.
