The other thing I wanted to see from the game but there's not a lot of is to do with the premise of the game.
Somehow you're reliving this weekend over and over again but details from the past change between runs.
* The MC appears completely unaware of all of this and I'm not sold on this idea. On one hand, it completely avoids the Groundhog day cliche of "I'm stuck in a time loop" and that's good because I don't need our character running around convincing everyone that something is weird. But on the other hand it seems weird to not address it. We're playing as the MC. We make decisions as the MC. We as players can use our information of having replayed multiple times to make these decisions but when the MC arrives they don't have the same excuses/reasons/foresight that we do so it can get really muddy when it comes to roleplaying as a character who has no information when the player has information. I'd like to see this addressed somehow. Maybe you get a visit from a goddess who gives you some mission or something but forbids you to tell anyone? Or maybe you get occasional scenes where your mind is wiped and there's this meta-story about what's going on behind the scenes and that leads to the climax of the story? Maybe the MC is in on it because they're a government agent? All of this would only need to show up once every handful of runs or perhaps anytime you make progress but it'd be neat to understand the premise of the game a bit more.
* I stand by my previous comment about BE and how this is an erotic game and people come here to jerk off...BUT the idea of small details from the past having a large impact today like we're Ashton Kutcher in the butterfly effect, is a cool one! It would be cool if we could alter all sorts of events but this game is focussed on corruption and I understand that really just means characters with increasingly flexible sexual appetites but it would be cool to see other changes. Like if Jenny never got so interested in books then maybe she wouldn't be as close with Lina. Or if Sammy had a different upbringing then maybe she wouldn't be so adamant about working out? Or maybe she'd be even more fanatical about it?
* Regardless, I'd like to see a little more than one line introducing the changes. For instance right now when you increase a character's corruption there's one line saying something along the lines of "And we were always this close and open with one another" but I think it'd be cool to see maybe a couple snapshots of you two in the past and then as the corruption increases, those snapshots from the past change. EG: At first there's a picture MC is standing beside Alex politely as the caption says "Me and my friend MC" at high school graduation. Then in a corrupted photo there's Alex sexually posing herself on the MC and it's titled, "BFF MC! Gonna miss you!" I recognise this seems like a lot of work :/
