Really nice artwork! Did you make it all for the jam? The music fits well, too. Gameplay wise, the combat system was very functional. I did experience some of the issues the other players did, but I was still able to complete the game. One I haven't seen mentioned was the UI sometimes being unresponsive when selecting an attack target (specifically, not moving the marker when I expect). All my cat names turned to "testing" in the final battle, too. Everything else felt pretty polished.
I'm impressed by the amount of work accomplished. Congrats to the team of two!
I have much more to say, but alas...
