I wanna preface this with a slight apology for the lengthiness but idk, feedback is important >.> idk <.<maybe not all >.<
But yea, I don't think its TOO boring. In fact, I initially thought it would feel grueling to have to pick repeatedly what you wanted to study or do but the existence of plotlines in the background kinda breaks up the mundanity in such a way that it feels like your constantly making your choices in anticipation of what you might run into next with any of the professors. I replayed the demo in several ways, first exploring how the food options or items in each shop affected the days. I was glad to see the main avatar switch between the outfits purchased for each class and to find that the books you bought could be used to study with. I also noticed that studying did change my grades which made me curious about what effects that could have on perhaps your relationships with each teacher and if it would prompt any secret actions. I found the food system somewhat amusing but dull at times. Sadly, price was really the only variable for the food but I still enjoyed imagining eating some of the options or even just laughing at my character for being forced to eat Pork Ramen or Leftovers for the 3rd day in a row.
Though it may have been a little grindy, I think the "promise" (or, rather the prospect) of some erotica may have dampened that for me personally. I mean some of us really focus well when we're trying to er, um.. enjoy things of this nature xD. I do appreciate that there are some actions only available at particular times of the day because it mimics life in a familiar way. But I do agree that it could be somewhat simplified (but hopefully not too simplified as I really do enjoy it as it is and I feel like I'm not the gamer I once was so, for something to feel a little fun despite the grindy nature, color me impressed).
Thanks for replying and Good Luck going forward!
