Unique concept. I was a little sad killing those bunnies though, haha. I think the game could have some kind of risk or a sense of urgency of sorts, because there is no danger per se. Some other considerations:
- As other people mentioned, there could be some adjustments to the hitbox
- Jumping (and the platform up there) have little use in the game
Other than that, the visuals are good, and so is the music. Good job!
