I wish I could give a 4.5/5 rating. Hell, I would even give it a 5, but there are two things that draw me back from giving a 5.
Art, animation, and H-scene features of the main girl are really solid. Solely in terms of Free-H capability, it's definitely up there, but still much behind something like Koikatsu Party.
Don't remember any of the music.
Gameplay is paced pretty well for the most part. And I say most, because my issues with it are solely there. Leveling up areas is a bit too technical, vague, and grindy at times.
At least from what I saw that was EN translated, it doesn't make it exactly clear how much you can level up in points per day for an area exactly. So you're left to guessing and grinding a bunch in a day, and this can get seriously repetitive if you're trying to get a sex feature. Some spots require certain toys in niche spots combined with other things to progress that area, and this isn't made clear.
The game also requires a little more mouse movement than I'd like, with the auto mode not really helping out enough.
TL was fine the whole way. I didn't notice anything that was difficult to understand.
If those issues are fine with the player, it's a solid experience.
