I tried to play this game a few times, and each time I had to stop. The obvious positive of the game is the art. I'm willing to bet it's what draws most people to it, and for good reason. It looks great. The gameplay needs work, but most reviewers already pointed that out. Having said that, I do think there are better pixel art games on this site (which I'm not allowed to name).
Now for the writing. I will preface this by saying that I know the characters don't stay 100% the same in the story, however, they still have their baseline archetypes that I will discuss. I'm increasingly becoming less and less tolerant of games that have "anime" or the honey-select style. The reason is that I noticed that a lot of games that have this art style use generic anime characters.
I keep seeing the same praise lobbed at these types of MC's. "OMG the MC is not a nice guy! It's so cool seeing an MC be tough for once!", etc etc etc. Meanwhile, every other anime-style game has this archetype of MC. It's not new at all. In fact, at this point, I'd say making an MC aggressively nice would be a breath of fresh air compared to all the "awesome cool cold steel the hedgeheg" style MC's I keep seeing in anime games.
Now I know what you're probably thinking. "It's a corruption game you idiot, The MC isn't supposed to be nice." I understand that, but that doesn't mean that the MC should therefore be a cardboard cutout of every other kind of corruption MC (especially ones with the anime aesthetic). In fact, I'd think it would be even more interesting if a game was made that could somehow make an MC try his hardest to be a nice person even though his actions cause corruption, but he was too psychopathic to understand. That's the opposite of what we get in this game and those like it.
I keep thinking of all the cringey anime I used to watch as a twelve-year-old and how "cool and dark" the characters were. Not to mention the copy-paste priestess character, the copy-paste fighter, etc.
I don't hate this game (In fact I wish the author luck going forward), but I do think it's overrated.
