A few things I'd suggest:
- I guess I really don't need to tell this, but adding any kind of music would help the game a lot. Though great and stylish art compensates for this issue.
- Adding a simple pause option would be great. I lost the first attempt because the game music was too loud initially and I didn't have any time to adjust it so it distracted me a lot.
Other than that, it's a funny game and an original idea.
