Beat the first two levels, got filtered by the rest.
The game has a very nice sense of speed. The 3rd and 5th level really show it in a very satisfactory way. The character despite being simple is cute and its animations are lively.
About the controls, I didn't find them too comfortable. I found myself falling down platforms a lot, either about to jump or landing on them. Having to land on a tiny platform at top speed while wrestling with the camera was too challenging for me.
I know the levels are small and easily repetable, but a checkpoint system for practicing difficult parts would be nice.
Nice game, it is a good base to keep building on.
