I really like the chosen art style for the game, coupled with the low light it really gives a low budget horror vibe.
The gameplay's fairly simple, but I do think the concept could be expanded on if you wanted to. As others have said, allowing for methodical movement really helps this kind of system.
There are a couple of bugs (no pun intended) but I'm sure these kind of things could be ironed out with a little more time.
Great job you guys, I enjoyed my quick playthrough!
