This certainly is a well produced game with lots of praise to be had. However there are also quite a few things I have Issues with. Let me break things down:
Gameplay:
This is pretty good. The difficulty is well balanced and you got all the things you would expect from an oldschool JRPG. From Random Quests to hidden chests in Dungeons to crazy ultimate weapons that you will scour the world for trying to locate their crafting Materials. There were a lot of different Systems to make use of in combat from various spells and abilitis to an absolutely enormous amount of accessories that grant various effects, making challenging difficult Bosses generally an interesting challenge. Honestly, if you strip all the Erotic Content aside, you are genuinely left with a decent short RPG in general. The downside of this tho is that it's not really a "walk from erotic scene to erotic scene" simulator. If you don't enjoy actually having to play the game, the best the game can offer is adjusting your levels in the Recollection Room to make combat trivial.
Story:
In a similar vein, the Story is not bad. You got a lot of interesting turns to it, and it even appears to be tying back to the developer's
previous game. There are a few decisions throughout the game that affect the story, mostly in the form of optional party members and/or things that will lock you out of the "good" ending, but it's not soo much that it becomes overwhelming to try and figure out what to do. It's nothing amazing, but for an ero RPG they clearly put some thought into it. Biggest issue I have is that I don't enjoy the Male Protagonist, who I think just comes off as "boring generic harem protagonist guy" but I'll fully admit this is likely personal bios since I really don't like male protagonists in general.
Erotic Scenes:
This is probably the weirdest part. Given the name, you'd assume that Personality Excretion is the main focus of the game. And it certainly has quite a few scenes. But really not that many in the grand scheme of things. Outside defeat scenes for a few enemies in the early game, there are maybe 3 or 4 scenes in the entire game that actually deal with this kink. So if this is the thing that made you check this game out, you might be a bit disappointed. Instead the game seems to be embracing the category of "unusual but not quite fucked up" kinks in general, having a focus on things like urination, pregnancy/childbirth, mild ryona, (light) personality excretion, baby play and nipple penetration, while shying away of more extreme kinks like gore, snuff, actual scat or the more "personality death" interpretations of personality excretion (in this setting it seems to be more of a "causes temporal confusion" kinda things).
In addition, I think the amount of H-Scenes is rather low, especially as you aproach the end game. And while there are up to 4 female characters accompaniying you on this journey, anyone but Slyvie herself gets 4 scenes at most.
Most of Sylvie's scenes also have a "low sanity" variation. But in my experience it's really not worth revisiting them all just to see it and instead you should just decide in the early game what character you want Sylvie to be and adjust her sanity to reflect that.
Translation:
For better or worse, this is a pretty good translation despite MTL. There were no unintelligible lines, and characters/places were translated consistently (at most the translation would call someone a "yuki-onna" in one line and then literally translate that as "snow woman" in the next). Some of the Items had odd names but nothing you couldn't understand.
All in all, 4/5.
If you enjoy kinks in the uncanny valley of "definetly not vanilla anymore but also not really fucked up yet", there is a lot for you this game. And while I personally think there should have been more, or at least more variety of, H-Scenes (and that given the title personality excretion should actually have played a part in more of them) But I still had a good time with this game.
