I'm glad you enjoyed playing as much as you did at least, and I'm well aware of the descriptions issue. I tried to lean into pico8's screen size limitation rather than implement an ugly hover text box for everything in the game, but it ended up being a more annoying cryptic rather than an amusing one. While I don't know what specific upgrade you're referring to with Rin, judging from your description, I can take a pretty good guess as to the route you opted for. I couldn't add more content due to the jam restrictions, but a prestige mechanic for ruined save files to make restarting less painful is an idea I've toyed with. Thank you for your feedback, I greatly appreciate it.
