Really interesting concept and pretty well executed. The only thing is the movement could be a little bit more consistent, because the game is very difficult, but sometimes it's a bit frustrating if you die even though you jumped.
I appreciate the level selection, so I could see all the levels even thought I couldn't finish all of them. In hindsight we should have done that too, since we get a lot of people saying they got stuck early on.
Also, if you have time, I would love to hear your thoughts on our game as well :D
