Just had a REALLY weird error, but shutting it down and reloading fixed it, so not sure if it's just a graphic glitch or what. Basically, it went from "normal" to "really weird color scheme". Given that shutting it down then starting it up fixed the issue, have no idea if it's on my end, or a Ren'py glitch, or what.
Do wonder why you made "sleep" so hard to learn, instead of 20 you made it 40 intelligence. Combined with moving willpower and intelligence into separate slots, that means it'll take a lot longer to learn it. Was it too OP at 20?
Otherwise I do like all the changes!
