Pros and cons are down below) Check out my vid here (likes and subs are highly appreciated)):
Advantages:
1. The game was so scary! The pacing was good and the ambiance was srong. I was afraid what's going to happen at the beginning of every night (except, maybe, the first night). Very well done!
2. The girl is very creepy. I think it's a very good character model. It reminded me a lot of Pacify, though. Still, she was very naturally animated and was very creepy. Sometimes if monsters are a bit funky then the game ceases to be scary. Well, this is not the case.
3. I loved how well-thought the nights are. Firstly, the player has to get acquinted with the place which helps out immensly during the following nights. I think, that's a very smart game design. Great job!
Disadvantages:
1. Though, being familiar with the place helped a lot, during some chapters it was still too dark. I wish it would be a tiniest bit brighter so at least the player would be able to know whether they are looking up or down. Once the player gets lost, it feels almost impossible to find the way back or to other rooms.
2. The notes are weird. Somehow the player can read them in pitch black AND how come it doesn't bother the main character that each day the notes appear to be different. So, someone comes at night, stared at the sleeping main character and leaves a creepy note. I think I would be bothered a bit if I were the main character.
3. I wish there were more endings. For example, one where the girl wins and one where the main character manages to destroy her. Maybe to reach good ending, the player would have to find additional notes and complete additional tasks each night or something like that. Anyway, that would add replayability to the game and would generally be awesome.
Overall:
That was just great! I was scared and amazed as I didn't expect the game to be as scary. Thank you so much for developing this masterpiece and reading my comment) I rate the game 5/5.
Hope my feedback was useful!
