okay I'm going to be honest, this game is pretty boring and it's actually more fun trying to figure out what the translation is talking about than playing the game. my main issues with the game are:
1: it is really fast, there's no build up to the ntr content it's basically step out the door, "oh hi next door neighbour", legs open, dick in, that's what it felt like.
2: way too easy to complete, find the pill of life (which it took me about 20 - 30 minutes at best), as soon as you know what works best against a monster (or spam ATK raising items) the fighting is easy to do.
3: I couldn't see the scenes as they happen, it just goes black and then I have to go to the house, go to the crystal, check if a new scene has appeared then choose the scene it's just needlessly complicated.
3: very few scenes to actually unlock (and not that good quality either).
4: unsatisfactory ending, it seems that even if you got all the scenes And raised the wife lewdness to HIGH levels it doesn't really do that much in the end.
It seems like this game tried to do both cucking AND cucked in the same game but didn't really manage to do either that well as a consequence. I know it's a free game and i shouldn't be so critical of it but i had to say my piece.
