I like the idea behind this one! Ended up playing a few rounds, best I did was 8 victims.
My main bit of feedback would be making things feel a bit more responsive, especially in regards to attacking the enemies. It wasn't a major damper on the experience, but I feel they could've been a lot more satisfying to slash through with some more clear feedback (e.g. flashing white when hit and playing some kind of damage sound)
Still, very good job! Enjoyed it a lot.
