This is a game that does a heck of a lot more than most RPGM-games to have a fleshed out gameplay-system, story and world, but unfortunately the game suffers from a lack of good pacing and polish.
The game in it's current state is extremely confusing, repetitive, grindy and has it's high points spread out very far apart, with some kinda bad "filler" sex-scenes mixed in with some fairly atmospheric ones. Facesitting and feet are plentiful, while other factors make less of an appearance.
The premise here reminds me of the Persona-game formula, with night-time and daytime sections, and trainable stats, but the world and the game's systems are unfortunately largely empty. The scope of the game was sized to be far larger than is comfortable, and it unfortunately shows. Huge empty environments, key gameplay-features hidden in far-flung corners of the empty map, lack of feedback on many things (most importantly the combat-status effects!), masses of pointless pedestrian NPC's filling up the space and wasting time, bosses that are statted out to act as roadblocks to facilitate aimless wandering, and of course the poor implementation of the sex-scenes.
Having played until the 10-hour mark, it is actually surprising that the game switches it up from the grind into an impromptu horror-section that is actually more engaging than the rest of the game, and even then is merely a long walk down empty corridors. Horror and unease is pretty much what this artstyle excels at, but the art can still be captivating as well.
The good parts are the variety of stats you could potentially develop, and the fantasies you could potentially explore, but right now it's kinda barren either way. The polish and quality of the content has (unsurprisingly) gone up as the updates have kept rolling, but that's not exactly an endorsement to plod through hours of middling school-sim and RPGM-walking.
