The game is simple and not too long, you advance the story by talking with the three ladies and completing some simple tasks. It's almost a VN, with a tiny bit of grind to pace the story and make it feel more like a game. Personally, I like that, it means that I can't really miss any scene. There are four time slots in each day, but time management doesn't really matters because there's no day count anyway, the time slots are only there to allow for different scenes. The only locations are in the house, which is a bit weird on a couple of occasions, like when you want to go to a restaurant but the car breaks, or when they mention the park or the beach but you never get to see them.
The story is quite cliché but well written, although I would've liked a slower burn: there's not much seduction going on except a bit from Julie, and almost zero incest taboo, they jump on MC's magic irresistible cock as soon as they can. Of course the default relations are crap like "maid" and "tutor" that make absolutely zero sense (a maid that scolds her client for not helping with the house chores? really???). The English is good, with the mandatory occasional "it's" instead of "its".
The UI is mostly good enough, which is quite the accomplishment considering that it's built on RPGM which is - in my opinion - atrocious.
I would've liked a bit more variety of body types (and some pubic hair if it's not asking too much), and I'm not a huge fan of the MC's small boy look (which is a common theme in Siren's games), but overall I find the art gorgeous and the scenes sexy. They are pretty vanilla but I don't mind that, I like vanilla.
The audio is nothing to scream miracle about, but it's OK: the sex scenes are voiced with moans and sounds, there's some music I turn down, and some standard RPGM menu sounds I could live without.
There's no gallery for the scenes (there's one with some sketches though), but it's OK because you can free roam and replay all of them.
Overall, I liked this game.
