Simple mechanic, nice graphics, and fun to play, I like it.
Was there some sort of special effect (particles or dust clouds) that was supposed to be played at the point where the player touches the platforms? Because I caught something in the upper left corner that looked like it and it appeared every time my player landed on the ground, but it seems that it was static and did not move with the player.
That's the only bug I encountered, overall, I enjoyed it :)
