Your certainly did a great job with the ambience; i could feel the tension as was going from room to room.
As others have said, however, the controls are a bit weird when entering and exiting rooms, and sometimes i ended up in a kind of loop…. I am not very bright.
I also expected everything to be controlled by keyboard and had a bit of trouble moving up and down the stairs because i did not understood at first that i had to click to the “up” and “down” labels. See? Not bright.
Other than that, i thought it was well done.
