I remembered seeing this on here forever ago, and thought to give it a try... and I'm really disappointed. The main disappointment is the fact that even though this came out in 2019, there is only a couple hours worth of content in it, and that's if you play slowly.
The story and characters are both really bland: MC falls into the ocean and then we fast forward into the future and he has a wife and kid, which is jarring for the player. We get snippets of what happened later on, but it would make much more sense to have us play through those parts of the story, as it would give us a chance to become familiarized with the setting. None of the characters have any depth; you literally tell some random girl you like her (even though you don't know her) and then she says, "this is the best day of my life" and then you bone... I wish that was a joke.
Despite this, some of the scenes are actually pretty hot. This is mainly because most characters are perverts, and none of them are overly possessive of the MC. They also just don't have a lot of sexual hang-ups in general, which means if you're given the option to do something risky, you should do it, because there's never any punishment for those actions.
The final thing worth mentioning is the renders. Personally, i find that most of them are just on the cusp of the uncanny valley (particularly in the eyes), but they still manage to be pretty erotic. The actual quality of the renders is pleasant to. Unfortunately, the animations aren't the greatest; they feel very rigid, and most of them are so slow even after the characters have "sped up" a couple times.
