Wow I can't believe I haven't rated this one yet. I played it a long time ago and recalled it as a 4 star game then. Since then it has mostly undergone quite a bit of polish, with some enhancements to content as well.
So, what is this game? It's technically an open world game, although your world is limited to a somewhat large passenger space ship (think middle class American house, in spaAaAace). You walk around the ship, open doors, interact with some things, mostly girls, all in first person animated view. These girls are almost undoubtedly supposed to be your mom, sister, and aunt, but you need to make sure you get an incest patched version for that to be true. You mom hasn't seen your dad in a year and is needy, your sister has repressed desires about you already, and your aunt is just a horny lady, so sex ensues and soon each one is moaning for you to cram as much of your seed into their womb as you can. We have not gotten to pregnancy yet but we are obviously going there. MC has discovered birth control pills so condoms come off, and he has discovered sugar pills to replace them with, but they do not do anything today.
All the sex scenes are highly animated, you have full camera control and a first person view. This game is definitely sex-first gameplay-second, which is perfect. Graphics are great, I love bigger-than-her-head boobs so I'm feeling that, and the personalities of the characters are cool too. The story is... perfect! It's nothing obsessively compelling but it's not trying to be. It works very well for its intended purpose and no more or no less. Dialog is well written (occasional typos but otherwise sound grammar).
So, what about the future? It's sort of at a critical point in my mind, a place where dev could keep true or royally fuck up. In short, the dev really needs to wrap this title up and there is a bit more he needs to do in order to tie all the ends up, but there is also plenty of room for him to make the mistake of greatly widening the world which will make it impossible to complete in a timely manner.
If we start seeing this game branch out, my rating would drop. I don't want to be introduced to a new race of aliens or more family members or etc. We have 4 sex interests today, lets max those out, knock them all up, make them have our babies, cuck the bad guys, and call it a day. That may very well be what the dev has planned, which I am assuming to be the case, thus my 5 star review.
