Ah, the joys of trying to throw together sufficient mechanics to allow for decent storytelling (to support the jam theme) in just five days. I've tried to weave together a dialogue system and a shop system in my jam attempt. It's currently hanging together so loosely and with such instability that I'm genuinely scared I'm going to bring the whole edifice crashing down with one bad script edit.
And yet, somehow, yes, it's still fun!
