Plays quite intuitively, with the un-wieldy controls being intentional and in line with the theme. Incrementing difficulty (rabbit spawns) and having variation in the kill moments (slow-mo) were nice presentation touches.
On one hand, the mechanics do not feel so innovative, but it also makes it easy to understand. I like that some attention was given to mixing things up in each aspect of the game, giving it a bit more personality & "juice."
Seems a solid case of keep-it-simple & polish. Nice work!
