I haven't played the demo, but I'm willing to give it a shot and report back! I just, as a general rule, don't tend to be attracted to the kind of character arcs and stories that go hand in hand with school games.
Don't get me wrong, I used to play them (my candy love comes to mind during my high school days), but I found my patience for certain tropes and stories running shorter as I got older so I stopped touching them, even in college setting sims. Also honestly I just feel... icky, dating ( fictionally) anyone under 18/19 at this point, even if the MC is of a similar age. I know it's irrational, but I've found it's just something that I personally struggle with now that I'm heading towards my mid 20s and would never, ever, date someone even below 20 in real life.
I don't know what to say on the social media presence (I'm not a creator so not familiar with the particular challenges that would be there unfortunately), except I don't think any update is a waste of time. I love hearing what's been going on, even if it's just that a scene got written or that you have a cropped background to share or something. It keeps me excited and in the forefront of my brain.
Regardless of what you do, I will absolutely check out the demo now because I realize my blanket ban is kind of unfair, especially since I've liked your other work so much. I'll also keep an eye out for news of the KS if you do one, I'd at the very least get a game tier, whatever that would be at.
