Yet again, a bunch of people complaining and trying to alpha-meme on a game clearly marked as NTR, with a suggestive description and posted by Saikey. Yes, I will pretend haters don't do this on purpose.
As others have said before, it seems like a copy of Indecent Wife Hana, while there is a good effort in Hanna's art, story and dialogue this just feels like a cash-grab: the game is way too short at the moment, the animations feel kind of weird at least for me, there is no portrait of Kenji or Rina when they are speaking and the story moves too fast without giving time for the player to digest everything that is happening. I would say the build here is more of a rushed proof-of-concept kind of thing than an actual release. So far the worst thing is the pacing though, for this kind of game going slow without being too slow is absolutely necessary.
