Thank you for your thoughts!
Yes, the sauna is still waiting to be used, but will also be used in future versions. And the "appearance" attribute can only be raised, but is currently unused as well. I implemented both primarily to test the mechanics.
Wonderful idea with the reverse use of the cleanliness mechanic. This would also suit Jessica, as she likes the MC rather strong and "manly". However, this could become a problem when a threesome content is introduced later: One girl likes the MC clean, the other doesn't. Would you then only have to be a bit dirty for both of them to want to have sex? But I will certainly think about it
In any case, I'm glad you like the game!
