Pros and cons are down below) Check out my vid (the game is the 3d there):
Advantages:
1. The house is very detailed and nice to look at. I enjoyed the visuals a lot.
2. I didn't expect what the concept would actually be and I loved it! It was strange and tricked my brain several times. I think that is amazing and could become a bigger project!
3. I liked the idea with the tapes, wish it would be used more and implemented some spoops) Still, cool.
Disadvantages:
1. It confuses that it is not enough to crouch to go in the vents. Because that makes the crouch button literally useless.
2. The layout of the house supposed to be strange but I didn't like that it had so many floors and a strange security code. Why did you have it if you did everything to be able to get out. That doesn't make sense but I think if this would be developed in a bigger thing than it would make more sense.
3. There are a couple of bugs: I could take the cover off the vents straight through the bookshelf in the 1st room. Also, I got stuck in the bathroom one time (you can see that in the video).
Overall:
Enjoyed that a lot! I wish to see something bigger coming out of this project. I think it has lots of potential. Still, the ending is lacking and the game could use a bit more polish. Keep up the great job! Can't wait for your next projects.
Hope my feedback was useful!
