I hear you. I think it's sorta refreshing, since zombies are meant to be a real threat. We're not supposed to be Zombieland/Dead Island/Dead Rising killing them like they're some sort of joke. It's more like RE1 where killing them is almost like a last resort and running away is a smarter prospect. Not many people like having that sense of helplessness, but then again, that's horror. Obviously, given it's likely an AI game made with barely any human thought, I don't think the dev really intended that, but just my thoughts.
While not great, the art wasn't completely terrible for me either. Since the game's still available on Dlsite to view for Western audiences, I'm wondering if it's actually NOT AI - Given the differences between this game's art and the circle's previous games' art, perhaps they just hired a new artist. I'm personally just more annoyed there's yet another NTR game. I don't mind the NTR myself and I understand I'm not the target demographic, but the market's really saturated with them, it seems.
