This is the only version I've uploaded to Itch.io, so there aren't any older builds to access. I could upload older ones if they're wanted, but honestly I'm not sure why because this version is the most feature-rich.
That was a planned feature for the game that would have had a whole slew of other options, like high score management, bug and glitch toggles, and some other stuff, but it never got implemented, so I took the text out. Even back in V0.36 that "settings" text was just there and didn't do anything haha
