Nice!
The music collab is very cool, thats so sweet :)
Improving the camera in conjunction with the movement could bring a lot to the game. Make the player faster with a nice gradual increase in speed if you travel in a straight line and move the camera in the same direction while getting faster. This should result in a juicy effect where you move faster and see more in front of you. I imagine that being kinda funny as well - rushing throught the maze to quickly collect all the nice apples
