Cute looking game. But there are some issues:
- As others have mentioned, the character feels like hes moving on ice, i second that.
- The character stucks on walls. In Unity you can fix that by assign your collider component a physics material.
- If you die, the music stops playing.
In general, the game was fun to play, but also a bit short. But still good job though.
EDIT: Forget about the second issue, i just now realized that it was intended.
