to me, what puts it above others is how fun the sex minigame is. most porn games have no interaction besides press next and read text. and the ones that do have gamefied sex, are terrible.
here you have some fun and control, and you can do alot of fun things like ass to mouth, i just wish oni added abit more, like deepthroating/throatfucking.
also, i feel like oni could add more fun things to do, maybe have stuff like a cafeteria, library and the lab.
imagine if you could earn money by helping in the lab, or in the cafeteria. and you could even have some fun with adding some cream to your girl's drink.
there could even be a minimal hunger mechanic. nothing absurd, but for example have your sex energy recharge slowdown if you are hungry, same for the girls,
meeting and befriending some of the girls is also a pain, meeting them in the library to study together would be a nice way to raise the love meter a bit so you can start asking to do stuff together.
same with the cafeteria, maybe they could be eating there, and you could sit near them to talk, and gain some early points.
finally, some of the girls could be tied to helping the lab, maybe they are having issues, and you can help them with your special dose.
oni could even genderbend beast, OR add mystique, and have her run the lab, and she tries to manipulate us into fcking the school up, but we end up fucking her instead.
imagine, she comes to seduce us, and get a taste of our power, but it works in reverse with her, making her unable to change unless we power her up, like an opposite jubilee.
when powered, we could have her copy other girls, as well, so we could fuck 2 of the same characters at the same time, like they are twins(we could even have them in diferent outfits/hair styles).
