Really interesting concept!
I had some troubles with the controls at first; the controls in game displayed the arrow keys, but for some reason they didn't work and it was W & S that was the interact buttons, but once i figured that out it worked good!
It was fun! Would've wanted a bit more feedback on clearing the level and getting players to the end, I assume that you didn't have time for that, but the music was nice and atmospheric :).
Small, neat little puzzle game!
