A very nice platformer! Some lags from world 2, but nothing bad, I also liked the fact to go up (level 2), and then down (level 3), with the mushrooms that are allies, and then malus! The music is not bad (what software did you use?), and the level design, especially on level 4 is well thought. I just add that I would have liked a pause menu, because to take the picture it was not obvious :D .
