I really like this mod, i would like to say some things if you don't mind:

There is no hustle animation & entrance animation, i think a good idea for them if you haven't thought of what they could be, is the entrance being them falling & causing a (small) shock wave & the hustle being flipping a coin before immediately catching it. or if you wanna do a meme, you can have them pull out the hamster from 5-2

I feel like the supers (excluding ultra pump) are a bit lacking in their... supernes... anyways, i got a idea for a universal super: refueling mode, instead of filling the super meter blood now heals for a short duration, (100 hp a pip) but will continual drain the super meter & will end after a duration ends or until super meter is empty.
i don't know if you will put that in or not, but if you do, i have also considered making the duration resetting for each pip of blood, so if you play aggressively, you can gain lots of hp. getting hit by the enemy though will kick you out of the mode.

another super idea is the ground-pound, which WILL launch the enemies into the air (but instead of arena wide, it has a small range) it does have a minimum height requirement though, or else it wont do anything. it also deals no damage, but it does stun.

if i helped with ideas, thank you for considering, if not... oh well. (not in a negative way)

P.S. for feed-backer, can a block deny damage, but a parry also heals 50? since parrying in ultrakill also heals you?
