really great response, thank you! And yes as a solo dev your time of course should be spent on the story and actually important things. I personally like the education level, as it makes the point that as you expand your powers and influence, you actually have responsibilities if you want to be good and do things right. it's a great way of showing, not just telling the burden of being "good" while still being fairly entertaining. If you want to be the evil sex god-king sure forget the college, the girls are only good for one thing so who cares if they are learning, maybe even add a shatter-esque way to skip the whole upkeep chore entirely for those who don't like it.
I love the world and characters, I enjoy the surprise of seeing special things on different days, and I really like seeing Lyx around town (please, I need more crazy witch-scientist goblin in my life, also I want to see what chaos would ensue were Lyx and Roxy to meet)
But yeah for me, the most boring and annoying part was the day/night cycle interrupting what I was doing, but then not having any other effect or impact besides places being open. It just feels like its the same week on repeat, so some slight change or something that happens monthly/bi-monthly (college exams, club events, harvest season? idk) would give a great feeling of time passing and the world being more alive.
You're absolutely right though, this is more of an after-main-story-development addition than something to be done soon. Keep on doing the wonderful job you are doing! (also donated because of your great response to my winging just so you know :D)
