I like the idea of it, albeit there are a few things that could need some improvements.
Mal0 is for me impossible to spot in Night 2. The only time I ever see her is when she is already in the room. In Night 1 I saw her a handful of times, though even then it was not possible for me to really grasp any movement patterns. Does she have patterns? I mean, I imagine she walks through the house and tries to reach the player, but most of the time she is never on any of the screens, making the video feed seem useless. The missing layout of the building makes it hard to imagine where the rooms are. I cannot tell if the Bathroom is on the upper floor or ground floor.
It would be good if Mal0 was either on one of the cameras or on the window at all times, just so the player can track her. Right now it feels extremely random. Is there any image sign or sound cue that shows that she moves? That could be helpful as well. Also, I wonder how she would appear on the window if she is outside to get up to look through the window. Maybe she opens windows inside the house as a checkpoint of sorts to slip out and try the bedroom window from outside? That could also help the player see where she was at.
The sex scene is nice overall, albeit the tongue seems to clip on the blowjob (though I only ever saw the blowjob to be fair). When the player cums inside there is no trace of any cum seen. And when the player cums outside, the cumshot is lacking. Usually cumshots in 3D almost never turn out well sadly, but I feel this one could use more work than regular 3D cumshots. No offense meant. Also, it is unclear to me when a player cums inside and outside as there doesn't seem to be a button for it. Is it at random?
Either way, I want to thank the dev for giving a demo of the game. It is nice to test a game out first and then decide if one wants to buy it. Right now the game is a pass for me. Like mentioned, I did get frustrated at the gameplay. xD
I hope this critique isn't off-putting. I do like the idea and it is quite neat for what it is. I just think there is definitely some room for improvement. I am interested in what you, the dev, will do from here on out, so I will follow. ^^
