Thank you so much for the positive feedback, I really appreciate it!
Regarding rollback in the mini-games : I'll think about it, but my original vision was to disable it so that players who want to play the mini-games aren't tempted to "cheat" and can keep that natural challenge aspect. That said, you can always save before the mini-game if you want to retry it.
As for the adult content in the gallery, some of these can be very small scenes. For example, the first two are related to Grace and require winning against her twice. But normally, they shouldn't be "hidden" - the choices leading to them should be fairly clear. That said, the guide suggestion has been requested before, so I'll definitely look into adding one. I'm also thinking about including the answers to the tests/quizzes in there as well.
Thanks again for taking the time to share your thoughts!
