Not bad! I always admire people who go for 3d, even in a simple game like this.
It took me a second to figure out what I had to do until I learned that spinning IS the thing you're supposed to do :P
The bones are here I think but I will say that there's probably a lot more that can be added to ''fill out'' the experience a bit more.
Also some small details for me: I noticed that after checking the computer the clock sounds effect in the background goes away and doesn't come back after you leave the screen and also I couldn't spot a signal that the computer was having errors but maybe that's on purpose and you just have to periodically check?
Overall; pretty good. Simple fnaf type of gameplay loop. Good job!
