Thanks for the game.
I like it a lot. I like the cute look of everything. The tune is also a bit relaxing.
Remember: if you make a game in pixel art style, implement pixel-perfect collision and controls. If you don't have pixel-perfect collision system and controls, don't annoying the player by requiring pixel-perfect moves. That's a little f-r-u-s-t-r-a-t-i-n-g.
I failed level 3-5 about 10 times. I will try to beat that fucking final jump later.
Anyway, this is is a very good game. Just remember that for the next time. There are many ways to create actual challenge to a player ;)
