Compared to their first game there are a lot more choices, and their artist has definitely improved his art. The game has both husband's and wife's POV; the sex scenes for now are from her point of view and how she started cheating on him, but I'm sure this is a build-up for the next versions of the game when he'll discover it and live the NTR.
For now, there's a good amount of scenes. In the gallery I saw they will be 35, a very ambitious number for a game developed by a small team. There's no voiceover, but I sincerely prefer it that way... the best voices are the Japanese ones, an English one would probably make me uncomfortable. The NTR is avoidable and I appreciate it, having the possibility of being able to avoid the tragedy makes it more engaging.
For now my vote is 5/5. Obviously there's always room for growth, but I could fill the lack of proper translations of the Japanese masterpieces (Anim/Pin-Point, etc). Can't wait to see their next update.
