I thoroughly love what I've played of this so far. I enjoy the writing, I enjoy the character interactions, this feels like an adult novel in a world I want to keep seeing. That being said, I do have a few suggestions for improving this for the future, just as a thing really.
1) Make the time limit optional/Give us more opportunities for progressing with characters beyond saturdays. I enjoy the concept of only being able to make progress on saturdays, I really do. But if you actually check the time properly, you can get about 5 characters maxed out if you're lucky, and while I enjoy the game, I'd be losing a lot of enjoyment for playing it over and over again.
2) Make the gallery actually work. I can understand it not working right now since you're still adding cg's and such, but it'd definitely be useful going through certain character's storylines and such, getting through and getting the lewds, and then having those in the gallery so that I can "appreciate" what I've gotten.
3) (temporarily) give us a warning if a character isn't fully finished yet. this is just a personal bugbear, but when I'm looking at a character like glynda or peachy and then find out they don't actually have anything beyond the first two saturday events, it gets quite sad and I feel like going back and not bothering with the characters until they're finished, so I can see an actual conclusion. Obviously when this is actually finished it won't matter anymore but it does right now.
4) Give us a couple hints as to how and when we can progress with other characters. The first time going through this, I had no idea characters and even interactions were gated behind time progressing, so I spent way too much time amping up my stats in useless areas when things were already good to go. Either let us know that things are gated with a tip screen or something, or for some characters, stop them from being gated on saturday so much.
5) Personal request, give me a harem ending. I'm a greedy bastard who enjoys all the female characters, and I want them all. This somewhat ties into the lack of time to actually explore all the characters in one single playthrough, because I don't want to play through this three or four times just to see what each different character does. Make it an optional thing, make it super difficult with required paths, I don't care. I'd rather it be difficult to achieve but possible and rewarding, even just an extra bonus of sorts compared to the actual endings than not have it at all considering your game is built around fooling around with multiple characters.
6) Fix ozpin. His character looks weird and that strange chin gives me ptsd. Not major, but at least make him look similar to the actual ozpin instead of looking like his jaw is lower than it should be and in an almost perpetual troll-faced grin.
7) Please keep working on this. I don't know if the creators would even look at this site or anything, but if they do, I truly appreciate how much time and effort you've put into this project, and I enjoy the new additions of CG's and such. I want this to finish, to be made and finished so I can play it through in all it's glory, enjoy the world of remnant and more.
8) (Bonus) Make more lewd cg please. I like what you've done with the amber stuff, if possible rework all the other lewds too, that would be awesome!
