Congrats on finishing the jam!
Played through and got quite a few upgrades. The art is very nice and clean and the music and sfx mesh well. The tank scared me lol I feel like the game could be improved by being a little bit more responsive - for example speeding up the animations when the enemies are hit. It's impressive that you even got character customization in here and coop!
Other places I think that could be improved is roll being on the L button/trigger instead of the L stick - it's a little slippery and awkward when you're moving. A map overlay or way point for the home location may help people who have difficulty memorizing layouts so they don't get lost and frustrated. It may also be nice to show the current score and health on screen. Also hats.
All in all great job!
