Ah, I see, no problem cause looking back on it I can see how the challenge wouldn't have much sauce unless there was forced higher teacher difficulty (which could potentially make the challenge borderline impossible with even less frequent items). Though, there could be an altered version too where theres no items at all with teachers being difficult but not impossible, giving enough challenge of trying to still escape them.
As for the eraser, that's pretty fair honestly. I wouldn't say that it makes no sense for it to exist though, at least in an instant universe way. Though if not for its original purpose, perhaps there could be another use for it one day, you never know!
As for the posters, I could help with those if you'd like! I like drawing and it could prolly help with my art block if you lmk specifics and details you'd like (if you want of course).
And sure! My discord username is actually the same as itchio display, pink_zazel. (My discord display name is sin. and I'm roboto147 on reddit with the same pink_zazel. display name, in case you'd use that instead.)
