The first 3 chapters are 5/5, like the reviews say, really good.
-the procedural school system is really unique, much better approach than in other school games, with much more mechanics, it's repetetive, and sometimes doesn't make sense because of random events not fitting each other, but the system is itself the next evolutionary step, it just needs more polishing here and there.
-also a lot of mechanics, sub/dom, choices, teacher-relations, romances, classes, school-reputation, minigames, secret agent-quests, thats a lot, which is 5/5-quality only based on the mechanics. A renpy game like this would be fantastic.
-but the contra is, after chapter 3, this all stops, then a new story starts, which ends all school-mechanics at once, and you have to read half a book of completely irrelevant text, that does not makes any sense anymore, I skipped nearly everything, and after that stopped playing, because it's a huge time-waste. So it's confusing and dissapointing, why throw a 5/5 game with perfect mechanics in trash like this? It's only dissapointing because it was so good before and you learn to love it. Maybe there will be an alternative ending of some sort, or something like part 2, with the old mechanics, this would easily solve the problem, because the first 3 chapters have a really good story. Renpy has also much better skip-systems, most of the time you get alternative versions of the procedural events, but even these repeat 3 times after some time. The strength is clearly that it does not escalate, and you need a sense of judging, but after that in chapter 4 it's just a random escalation-tunnel-system, so choices do not matter anymore, nor does anything about the school or the relationships.
-but besides all the critique, the animation and art is also great, it says it's from honey select 2, so it looks old, maybe the dev doesn't have 10.000 assets, the game shows clearly that the dev is skilled, and it's worth playing solely for the lezdom, lez-romance scenes, because even with outdated animations it's all interesting and good. For lesbian content still a must-play, I would say, I do not regret playing it, the world is also funny, all girls have only girlfriends, and it's normal to have 2 mums, the police-girls are all female of course, and more, I never saw a game with such a good lesbian-setup.
