Okay so having played through all the routes I'm gonna give my thoughts on the game. When I first started playing I wanted to be as distanced from the MC as a player could be, but since he was pretty much in the game for the same reason I was, he quickly grew on me. Now for those that don't like NTR, this is the full on deal you have been warned. The MC, as your actual avatar, gets cucked hard if you go down that route. In fact that ending pretty much rubs your face in it and it did get to me. A bit of background is that I dislike NTR so that route wasn't enjoyable for me though I did it because the CGs were very nice. Now, as for why I still went through with it was because NTR is a sub genre of corruption, and other scenarios (like cheating, stealing) gets lumped in and those routes I enjoy and usually dig into the NTR tags in order to find those gems. But that aside, my only gripe is my distaste for NTR, and I will not fault the game for delivering it (and it does so competently). In all it does get my recommendation because the characters are charming, the MC is as I said, in it for the same reason you are and all endings are the direct result of the player's decisions. The H content is also nice in that its peppered decently around the game and you can choose to actively pursue them or ignore them in favor of progress instead. Overall it was an enjoyable game, even if part of if was true NTR. In all I played the "Return Home" route then the "Demon Lord" route, and finally the "Cucked" route (Though I went back and did the Home route cause I liked that ending).
As for the translation itself. It is competent. It was enough that you can enjoy it and since I skim texts I didn't notice any mistakes.
