H scenes are rather generic but there's a satisfying feeling of doing them with a character of your liking, be it from video games or anime. The character designer is solid enough to make most characters you want and there are plenty of mods and add-ons for it, so if you are into the character creation, its a pretty solid option.
Worth mentioning that exploring and running around the island strangely comfy and there are even a couple secrets to find here and there.
All in all, a pretty solid game from Illusion and still worth trying, even when newer flashier games like Koikatsu or Honey Select 2 exist. Make sure to find a decent mod/character pack.
