Quite an interesting game! The concept is funny and challenging, the graphics and physics are good, the levels are cleverly designed, overall a great job! I would just suggest you:
- Remove the bored animations from the beginning, it's confusing.
- Make the level restart automatically as soon as the head is out of the screen.
- Make the Restart level button more visible.
- If I go to level select after a level, change/remove the music automatically
Great game and Good luck! :)
