An ambitious effort, but sadly fails to deliver.
(Review of Act 1 only)
Feels like an amateur writer's private self-insert fetish fantasy. As the player, you have zero agency - this is the main character's story, and you're just along for the ride. Unfortunately, despite the game's best efforts (and many hours of dialogue), the writing just isn't capable of making any of these characters particularly interesting or realistic. Similarly, there's a whole detailed world with a backstory and everything, which we're forced to spend quite a lot of time learning about, but it's all pretty shallow, basic fantasy tropes.
Gameplay consists of 90% standard visual novel dialogue. There are occasional choices, but they feel exceedingly token - mostly variations of "do you want to see this sex scene that's obviously about to happen?" Despite being technically a sandbox roleplaying game, it never feels like you have any say in how the story goes; you're forced to watch as the main character makes his own choices, while the player is left with the crumbs. Example: after a time skip early in the game, your character gets a girlfriend, who remains your girlfriend for the entire plot. This happens entirely off-screen, and you're never given any kind of choice in the matter, even if you choose to pursue any of the other dozens of love interests. The author assumes that of course you're interested in this girl, why wouldn't you be?
Of the remaining 10% of the game, half is a "sandbox" where 9 out of 10 options are "You clicked on the wrong location; try clicking other locations until you stumble upon the one the author expected you to telepathically know is the right one." The other half is surprisingly extensive combat system, featuring dozens of monsters and spells... that ultimately all do exactly the same thing. Once again, it's clear that a lot of effort was put into the combat, but without any understanding of what makes a combat system interesting. It's a shame, too; there was a lot of potential in having your magic influence the plot, but that never once manifested. You might think maxing out mind-control magic would let you manipulate love interests, for example, but no; your world-record-shattering magical skills are mentioned a lot, but never used.
If you manage to put up with all of this for the sake of the sex scenes, you'll probably be disappointed there, too. Once again, there's a decent quantity of them, with reasonably nice graphics. But they're very mechanical; a few renders of a naked 3d model in basic poses, no artistry, no passion, no sexiness. And once again, it's very much the author who chooses who and how you fuck. You weren't interested in this love interst? Too bad!
Overall, the game deserves applause for the amount of effort it put in. But all the effort in the world can't make up for amateur writing and direction.
