great work! music, visuals etc and game mechanics!
just one thing: riding the walls it's kinda weird when he jumps too far of the edge and you need to go back to the same spot... it could be a little smoother this jump-off.
I got a liitle confused and annoyed in one particular area where it jumped off the edge-climbing-flowers/grass and the screen kept changing up and down, because it was in between two partitions lol
also I discovered a cheat-bug: accidentally (when going down with the camera) I got stuck in one of the growing path-thingies (yes, on the little pixel just aside this growing thing) and it was too way down to go back up and the water just aside, down bellow (so I couldn't go back to a safe place and my game was completely over, because I couldn't jump and grow mid-air the thingies).
