Pretty great game, but with (in my opinion) several flaws.
The first one is that you have a *very* limited number of days and actions and it's impossible to see/get everything in one run. Not even lore.
If you speak with the councilors for lore, you miss out of advancing relationships with the girls. Even if you focus exclusively on the girls, it's impossible to get all scenes in one go. Massive annoyance factor.
Second flaw and massive annoyance factor is that the gallery only has the scenes that you unlocked in your LATEST playthrough. So if on your 1st run you got 2 scenes, then on the second run you got 1 scene with a character you hadn't unlocked the scenes for prior, if you go to the gallery after that second playthrough you'll only have that one scene from the latest playthrough unlocked (TL;DR the unlocking scenes are directly dependent on your latest playthrough save).
Third flaw is overall system navigation. I found the system itself (including but not limited to how the saving system works) to be very cumbersome and annoying to use. Likely because I've become accostumed to how simple, quick and easy it is on most Ren'Py titles.
4th isn't much of a flaw, just a minor annoyance - when you boot up the game for the first time everything is in Russian - and I understand none of it. It gets confusing really quickly. A simple language selector appearing as soon as you boot up the game solves that instantly.
Other than those things, the game is quite charming and interesting. I like some characters a lot, dislike others (Sora in particular. She's hot, but she's also a massive hoe, even if it lines up with the internal established lore and culture of her place. Still dislike it, but if the option to "tame" her or turn her into some sort of submissive "pet"/"toy" gets implemented, I'd like that).
Kudos for what it's there atm, and I'm looking forward for more!
