I know how it feels to not have been able to finish the project, I'll give feedback where I can though. The premise is a little...odd? It seems like you're just murdering drunk people? Or is your character the drunk one?
Anyways, SpriteShake can be a real handy extension for game feel. Making the characters shake when you hit them, along side the blood that is being spawned, can add much more of an impact to your swings. This and using tween to shrink/grow the sprite quickly.
I also wish I knew what the bar on the right does.
