This one was one of my favorite games for the Jam. The only thing that annoyed me was the use of many controls, I know you had to do it like that and you made an awesoem idea with that, in other way would be really annoying, great job with that. But the stones going up and down, makes me really crazy because the acceleration is really low but the breaks are even more slowler :(
Other than that, the art is really awesome, the idea was magnific and the code was great.
Good luck in the jam!
