Excellent game. The feedback is really well done, between animations and sounds. The gameplay is easy to get and there isn't unnessecary controls. Keep going, I'll buy it on steam at the release.
A few recommendations if I can, just for improving the game and I'm aware it can be on the to do list.
Sometimes the powerup like the apple or the skull spawns outside of the visible screen at the bottom of the map and it can be hard to the catch them as it's impossible to really see the character. Also sometimes all sounds stops playing while another is playing (like the horn when collecting a skull), the sounds are a really good audio feedback.
