It's funny because Bunnykill is itself a tribute to "Madness Combat". This is a tribute to a tribute! I admit that this isn't great. I mean, it's just you killing people over and over. At least the enemies are different. It's too simple.
Despite this, it's still quite fun. I mean, I love the Bunnykill series. The designs are pretty neat. I don't even know how I'm losing health. It's pretty elaborate.
