Thanks for the explanation! Would you believe I didn't realize "colleague" is probably just a typo until right not? I even played the game with the barebones college section a few years ago. Man, do I feel stupid now =D
Makes total sense though. From what I've heard, Steam curators follow a hard "no school-like environments in NSFW games" rule.
And I get that the devs probably don't have the funds to create two separate builds, but it's still a bummer they have to change their game on Itch just to hopefully not get rejected by Steam this time around...
