Must say i'm a fan of slow burning games with small changes in dialogues and scenes during your path of corrupting girls. You gain their trust/corruption and get different reaction every next time you speak with them (in dialogues and scenes). So characters become more and more open to you and your actions and SerialNumberComics good in it, but...
There are tons of pics, good looking models, really hot scenes but god it's hard to stop thinking that you are doing something wrong, because some scenes require hundreds of relationship points and you can easily lose your few tens if you make a mistake. Every day you will lose 5-10 points just because it is a part of "balance". At some point it was almost unpossible to play (and enjoy) the game without reducing subtractable points by modding newdays.rpy file. It is a good porn material, but god it's just terribly balanced as a game.
