Nice music and art - slightly gruesome but cool idea. The movement feels nice, if a little fast, and the bunnies look cute and cuddly and move in accurate bunny fashion. As firebelly said a bigger hitbox would be good, and to make the game more challenging over time I think you should start with more bunnies then decrease the number so that you have to chase them around. And definitely make it so that the bunnies run away from you instead of coming towards you (not because that makes it easier but because i feel rlly bad killing them when they are all trusting to me D; )
