(written for v0.91)
Story: writing is weak, and the bad translation doesn't help much.
Art: the two main girls are pretty cute, but almost everything else is unbearably ugly. At one point the MC has sex with a dog that is literally a png on your screen.
Ero: the game is delivering its events by means of corruption, and it is done shockingly well. The gradual escalation, as well as the pacing of these events is shockingly wonderful. You learn a new "skill" and you are willing to accept much more to be done to you by your teacher, by your boss, etc. Every small event that doesn't advance the story and just solidifies the current norm is wonderful.
After a while the progress just stops though. Despite doing insane corruption advancements, you get 0 new interactions with boss very early on. Your teacher has more events but also stops rather abruptly.
At one point your character starts wearing makeup and contact lenses, and even gets new outfits, but these can never be seen outside of like 2 story events.
Mechanics:
As a player, you must manage your time, of which you have 0 indication for where you are in the day.
You must take showers, which only have story meaning in the first hour in the game and never again. Showers can be ignored but the MC complains and it can be annoying.
You must eat at least every few days. You are stopped through your progress if you don't eat in time. So far in my 6 hours or so, there was exactly 1 kitchen event, and not even that was tied to her eating. There may have been plans for it before, but the whole mechanic currently is a waste of time.
You must grind for money. Grinding is slow and exhausting, which fits the story well. But even as you get better at sex, you still never get job improvements (except for a meager 50 bucks a week bonus). It just feels like a wasted opportunity.
Sometimes you get a deadline to do something. Grandpa gives you a month to gather 300 bucks. Even if you have the money ready the next day, you cannot progress the story until that deadline is actually reached. So you just sit there skipping time.
Another mechanic is corruption points. These should just be removed. At the early game these are pointlessly grindy. At the midgame you just rack them up normally with no effort just from playing the game. This also stops being a requirement, so by late game you really cannot tell if these points even do anything.
The final badly designed mechanic is grades. It is simple, you study or go to school to maintain your grade, or else you get in trouble. You spend tons of effort to keep your grade up, until suddenly you are required to fail, until you are required to have high grades... Both raising and lowering the grade is excruciatingly slow. You also have to balance your mornings between making money and going to school, it is mitigated by doing favors for the teacher. Your favors become more and more corrupted, but despite doing bigger favors, you don't get any more points.
Studying is just broken, if you leave your room once, you cannot study anymore for the day. Your grades also decay over weekend, even though you cannot go to school on those days.
The game is best at the midway, when you don't jsut grind for one thing, but unlock more events every week. At one point I had walks with dad, training with grandpa, random assaults by teacher, all in the same day. That was the only time when gameplay didn't feel soulsuckingly exhausting.
It is a shockingly good corruption game, crippled by badly designed game mechanics.
