Relly nice pixel art and music. The animations are adding a lot of great feel to jumping and running. Te movement in itself is really satysfying. My highscore is 1949.
I'm not sure about the idea of "3 lifes" in this type of game, and falling after loosing (a couple of times when i was thrown down after touching the water, it was imposibble to climb back, because the falling blocks that were there before have fallen down).
