This was my favorite game of the jam so far. I actually wanted to keep playing rather than making myself play so I could review the game! The only thing, and I didn't mind this, was that I never ended up upgrading my movespeed at all because the main limiting factor was the battle time. So maybe upgrade attackspeed? like not make you just attack faster but make battles progress faster. That may be kind of hard to implement tho idk haha.
Please check out my game and lmk what you think!
