I’m hoping to find a game but it’s very hard when the tags seem rather common and I can’t remember the name.
It was a “game” in as far as you could visit different rooms at different times of day and talk to the NPCs if they were there, like Battle of the Bulges, 3d models but with the stand out feature that they were kinda “chalky” and kind of low quality.
The set up is MC (possibly shota) is on vacation with his mother, you can swap between your room, the pool, the beach, a local store and later you could go to a native village on an island nearby.
It focused mostly on the MC and mom but their was also a friend of the MC, a short haired fat boy that would hit on your mother at the pool, but you had the option to just talk to him, say it’s cool or not and he totally respects you. Friends sister was also a character and you had the option to arrange with the natives to kidnap her and take her to their chief, a shota and then had the option to rescue her or not.
Also one last major stand out moment was at night you could try peek in on the other hotel rooms and one interaction was a strange man in a rabbit suit appears and says something non sensical.
