Glad you had fun!
I did actually tweak the hit detection a few times during this jam. I kept trying to make it more and more generous to you since you're having to control 4 players at a time and can't be super accurate the whole time. I guess I tweaked it a bit too much. As it is right now when you attack the sword hit box and your hit box will do damage to enemies (originally it was just the sword). You also can't get hit by an enemy for 0.5 seconds after you hit them and they can also not hit you for 0.5 seconds after they spawn. I did a lot of stuff like that and tweaking those numbers till I got something that was not super brutal since you won't be able to pay enough attention to a single character to be able to withstand brutal.
I'll have to do some more tweaking of it of course if I want to make it a full game so thanks for telling me it doesn't seem right to you. I'll try to keep on tweaking it.
