Invisibility + censorship ruins everything, the product could've been a lot better with just that being fixed. All BDSM stuff is optional, which is nice imo. Actually it's not a game (and not a novel), rather a set of videos, with some interface to switch between them.
If some of the future devs read that - just add some more quick story to a something like that. Just to make one PERCEIVE her as mother (and not only as female body renders) by various occurencies throughout dialogues, with appropriate behaviour. And instant gratification fans like me will be happy.
