ahh it's super cool, reminds me of portal. i played it on stream with crafty:

Neat concept, I really liked the try things out -> fail -> try again gameplay loop; it never really felt like I was failing, since every time I did I learned more of the level! I would've loved to see more to the game too, with more level layouts, obstacles, even multiple paths to the end, though what there is now definitely proves the concept! The sound design was something I particularly liked, since it added a lot to the ominous factory vibe of the game - and the sounds coming from different directions in the scene was a great way to help with visualising the level. Nice work on the game, it was a fun experience!

Interesting concept. I would suggest starting the level hidden with the light on so you can see what is going on and then take an action to turn it off before you explore. Other than that making use of audio queues when in the dark could really add to the feel of it and make you feel a bit more control when in the dark. I could see some fun level designs with this mechanic. 

Downloaded so I could see the lasers. 
Won on my second try by not turning on the light and running straight to the exit. It was a fun concept. Could definitely work as a more developed game. It would be good to have more levels with interesting designs. The biggest obstacle was the claw in the dark but I could see when it was in front as it would block the exit sign light. The conveyor belts could be a cool addition if they moved.

Died a bunch, but was quite fun to play! Good job!

A neat 3d first person game, lots of assets that seem like they took a lot of work to create. The flashlight adds to a sense of panic in trying to escape, very well done!
