There is no other way to put it, is game is garbage.
You play as the most stupid person on Earth (and now on space too). The MC is suppose to be mechanic of sorts what may lead you to believe he is smart, he is not. He fails to understand anything said to him, even when is related to mechanical devices like how a bracelet with blinking lead works, it just blink with a color depending on what is nearby.
The female characters are interchangeable, they have no personality other than being annoying. The game could have just one girl and still would play basically the same. The main love interest is the most annoying of them all partly because she has the most dialogue.
The choices are non existent to an infuriating point, wanna split the group or stay together? Doesn't matter what the player choice the MC will split the group. Honestly I feel it would be better as a kinetic novel rather than what we got, at least if it was the player wouldn't feel cheated for seeing his choices being overwritten by the developer.
The story is not original but I could look pass that if it was well presented, it is not. Everyone save one character speak like a anime high schooler, what makes no sense because the game is set on a futuristic wild west, something like mad max. In a setting like that the characters would be more mature doing to what they have to endure on day to day basis but instead they are less mature, the only character who acts like his age is George, a non romanceable character, that should be telling of the quality of the dialogue.
The player is also forced to listen to the thoughts of the MC and he has thoughts about everything but only to point out the obvious or what is already established. Telling what was already established is apparent the way this game choose to tell his story, the worst offender being a flashback from a scene that had just happened, literally the MC black out then he wake and remember how he blackout by replaying the scene again just in case the player forgot. The effect of that is the game moves at snail pace with no new information added.
The sex scenes are quite average for porn games, not bad but not good either.
The game has a nice GUI though, and the save system is quite neat and easy to organize, but considering how bad everything else, I doubt anyone playing would wanna to revisit a scene.
