Really love swapping between the council members, I think that mechanic in itself can go very far! And good job on the art!
Have to second that the maps are a little too big - I was optimizing my movement by swapping to Bae/Mumei to get speed boosts to move around quick, but still could only get like 1 and a half levels done. Definitely would try to tone down the map size a bit so you're actively gaining time by playing well, and not losing it walking between rooms (or just make it so you don't lose time outside of combat?)
I noticed at one point all my controls got swapped? I think this might have been one of Bae's debuffs, but it was just permanently inverted and that was really disorienting cause it was near the end of my run.
But there's some solid foundation here and some interesting stuff to work with, and it sounds like the team is planning to come back after the jam and add more content, so it'll be great to return and see what's changed. Good work!
