This is one of those few rare gems that you just happen to stumble upon while scrolling through this page. I think this game would've been much bigger if it had better producer since the beginning, and it didn't feature NTR (I'm not against this kink, yet it seems very hated in this community). Now there are a lot of aspects that to hold this game down, but it definitely deserves praise for trying to tell a different and unique story, with surprisingly good twists and turns, albeit with poor character development on the side.
When the game first started, it really presented itself to be kind of passable, but that diminished quickly after learning a few aspects of the story. The game basically tells the story of the MC agreeing to be a part of an experiment abroad a spaceship with his wife and 2 daughters. Events transpire and certain aspects changes as he learns new information about the experiment. Now onto the bad and good aspects of the game (might be minor spoilers)
The good:
-NTR is well handled. There is an option to turn it off at the start, and there usually is a choice leading to NTR rather than it being forced upon you. The game CAN be played completely without any NTR scenes, although you might still hear or know about some NTR things happening, rather than seeing. As for the NTR scenes, they are pretty good for people who enjoy NTR, but i feel like they sort of go missing later on in the game, to the point of non-existent.
-The renders get much better later on, at around the 75% mark. At first it really didn't look impressive, and cum straight up looked like paint, especially on the darker characters. This was changed later on and cum looked much better.
-A decent amount of characters, not a lot, but just enough. And they mostly look really good, even some of the parody characters look quite good in the game.
-The overall plot really pushed to tell a story, rather than just blending in with other p-games and their basic story telling. Here there is an overall arc, and even full circles of events that you learn as you play along. The ideas and story does feel like it followed a structure, or at least it was well thought out.
The bad:
-As mentioned before, the game didn't look all that impressive when it first started. The lighting and quality felt a bit off, so it was nice this was changed later on.
-Most of the characters barely have any screen time, especially the family of the MC. This becomes even worse when the MC decides to ditch the ship and go to another place, and a whole new cast of characters are introduced, who all have more screen time than people on the ship, yet it still didn't feel like it was enough to really connect to any character.
-Game length is disappointing. I honestly wish the game was much longer, with way more content so that all the characters get the screen time they deserve
-One of the best endings in p-games in general, but very poorly handled. The plot written for it was great, but the actual execution was just disappointing. After being separated from the characters you knew all along from the start for about half the game length, you finally meet up with them again at the end, and all you get is a few lines of dialogue for each character and then poof, the game ends. The actual journey to get to the end was okay, but the ending itself is just not good. Why are there no porn scenes in a porn-game ending? It's like you finally get all these characters together expecting a few porn scenes, and then the game just goes "nope bye bye". I really wish the dev of the game would just add an epilogue to the game, that would really negate a lot of the negatives for this game.
TL;DR: Game might be good if you can overlook the rushed ending and the kind of boring beginning, and are looking for a change of pace from all the Harem games with boring plotlines
