You awaken in a strange mansion.. how do you got there, and who is writing the strange letters you are finding?
Music: 9/10
Just simply because I think you used Penumbra music in this throughout the beginning of the story, which is a major plus to me! I could be wrong though. You actually used music and sounds unlike other stories where there is no music or sounds at all. You used variety, ranging from different games (I think..) to not using the same soundtrack through the whole story.
Story: 5/10
The story was like most stories. You're tapped in a house and you need to escape. Only to captured yet again.
Lighting: 8.6/10
Excellent lighting, however, it was very light in some places. To be more specific, near the end when you get captured.
Scares: 7.8/10
The scares were OK. The "jumpscare" was rather funny. I wasn't paying attention when the naked guy flew from the closet, and when I turned around, it was glitched in a wall. That was pretty funny. I like the monsters and it just wasn't all Grunts. Bonus points!
Puzzles: 5.9/10
Not too much for puzzles, just a bunch of key puzzles with pulling some levers and avoiding monsters. That's the gist/jist of it.
Atmosphere: 7/10
It was nice. Although, I'd add some particles for extra effect. Like I said previously, the lighting was great and it helped the atmosphere nicely.
Overall: 8.9/10
I really liked what you did with this story. It also wasn't one of those stories that just seemed to drag on unlike other stories where its naked guy after naked guy, monster after monster, and well, you get the idea.
I liked the music, puzzles were easy, scares and atmosphere were nice and the lighting was great. I'd change the story though so its not "I'm stuck in a house. Help." type of story. Nonetheless, it was a fairly good story and I'm looking forward for more of your content.
