Fun little game it needs a little bit more polished but I totally understand that in the jam you can lack the time. Here are some problems I noticed if it can help you for your next game/update :
-There is a problem of clarity with the enemies corpses, maybe they should disapear after a certain time
-The walk animation of the character are playing even when they are at a complete stop
-It's easy to beat all the enemies even while playing only one character
