That bug seems to happen if you already paid them off.
I think the game looks promising. In some cases for the art I think it looks nice, especially the normal full body portraits. However from some angles there's a lot of anatomical issues and jank. I'm not sure if you're using reference to paint from, but I think that'd be a good call to make.
There's also a LOT of grammatical errors. Honestly I'd recommend running your sentences through something like chat GPT just for "clean up".
I'm not really a fan of the combat system, but it's not bad enough that I'd just avoid the game because of it. However if the fights got harder and more complicated I have a feeling it could get a bit unbearable. RPG Maker is clunky at the best of times, so the simpler the better honestly.
Overall I'm interested to see what happens.
