Yeah, she is definitely dumb but it's something I expect of this kind of game (not that it's something I want to see). As for the NTR, I don't mind. Not only I'm not the one being cucked but also, I don't think it is netorare when the mother isn't in a relationship with her son.
Overall, correct update. I mean, it's not really well written, she looks bad sometimes, some scenes are dumb (the sausage thing, I thought it was dumb in Sarah's life, it's dumb here too) but it does what I expect of it and it has a lot of content for a free first chapter. There is one thing I hate though. Why give us a choice when the results is the same for both options ? It feels like a Telltales game.
But still, I'll follow the developpement of this game.
