I'm not much of a horror games player, so the jump scares did get me. I knew that they were just untextured models and I'm just a tester, but the sounds and stuff were done well enough to cause some proper goosepumps and jumpiness in me :D.
So well done! The premise is quite clever as well.
It would have been cool, if I had even more commands that I could do.
Overall a great job!
