Well, first of all, there are no 'like' buttons here I played the first 10 levels and it works pretty well. The only thing I dislike are the almost pixel perfect jumps, like the gaps in level 8 and the tight hole in level 9, these are rather annoying than challenging. Maybe you can improve the graphics a bit, especially the font, but that's just cause I don't like the standard sprite font. Other than that I can only say it's a good game. It works fine and I found it fun and challenging.
A tip though: If you want people to play your game you must bring it to them. So uploading it to e.g. Scirra Arcade is a great start.
