I won't comment about the NTR, personally I like it, but what I hate is when developers make sandbox games with no content, the only purpose of the sandbox is that you grind materials and food, you have a limited time to collect things, because with every movement it gets more late and most of the time the places you go have nothing, so you have to grind for days until you get something. And the game is grindy as fuck even if cheat to get more food, wood, etc, because you have some interactions every 2 days or so, if you want to put sunscreen in your mom, she will let you, but the next day she doesn't want it, so you have to skip all the day to do it again. The most grindy part of the game is the food part, why the fuck we have to make them eat every single day?? and like 3 times at the day?? It becomes repetitive really fast. This game is a grind fest.
And I didn't talked about the teasing, full of cliches, where the mom gets drunk, she is horny and wants to make out or have sex with the son, but in that precise moment she fall sleep. The MC is a cliche too, he is horny for his mother and he is so stupid that he gets himself in stupid situations or making stupid plans to fuck her, more of one time he talks to her like she was a prostitute and not his mother. The MC is supposed to be a genius but he is stupid and contradict himself, at the start of the game he say that maybe the family is in other part of the island, but later when his mom tell him that she saw a person, he tells that they are in a desert island, is impossible that she saw someone.
