As a horror game, it really needs the sound for the ambience to be complete. I think you got something interesting here. With a little more work it could be an interesting game. I really like top-down view like Teleglitch. I was not able to find the yellow and green door button, but it could be that I'm also tired lol
The pull mechanic is interesting although it could use some tweaking because pulling too fast automatically makes you release the objects and is confusing as some stuff needs you to move much more carefully in order to pull.
It needs a clear objective: aside from seeing buttons and doors, I don't know what I'm supposed to do, and there is no information about that in the level either, no texts to put me in perspective of what exactly I'm doing there.
I would love to see this game completed. I'm very fan of the horror genre. Best of luck!
