Cool game man. I liked it. Peaceful music too ;). I don't have anything particular to say. I really enjoyed the game. It was challenging at some parts. Especially when you missed a jump and you have to start over and wait to be on the good side before jumping again. :D
In addition, it's true it will work well on mobile devices. I will suggest to change the background of a level when the level is done though. It's just a visual thing but for the player, it's always good ;). By the way, feel free to try also my game and leave me some comments. I will appreciate. You can play it through my signature.
Hope this helps!
