I like this one a lot. Really satisfying collecting the souls! The art of the reaper is also really nice along with the cute souls. I *almost* feel bad for reaping them if they weren't trying to kill me too.
Between rounds however some of the enemies will stick around but are unable to be hit, or be hit by. You also left some debug tool in by, which I assume was an accident, because I pressed the d key by accident it started showing the trigger boxes and position data.
