Hey, good idea for the light-creating enemies, and (if I am understanding the puzzles right,) the levers that shut off the lights but open the door. Some things to fix/criticisms, if you are still looking for them:
-Unless there is something wrong with my speakers, I don't think your game has any sound. This begs the question, why do you want us to rate you on sound?
-I don't know how you did animation, but if you are using Unity, I would highly recommend checking out the animator feature: http://unity3d.com/learn/tutorials/projects/stealth/player-animator-controller, or you can see an example of how I did it:http://ludumdare.com/compo/ludum-dare-32/?action=preview&uid=37149
I noticed quite a few instances in which I was jumping but it showed me running, or running and I looked like I was just standing there, et cetera, so you might want to at least take a quick peek, even though it can be confusing at first.
-I ended up getting stuck on a light-bug with 6 legs (and had to restart, twice) when I was trying to get to a lever in the corner that he was guarding. Maybe make it so that you move away from him when he touches you or something, so you don't get stuck on top of him.
Yeah, that's all I could find. Cool idea for a game, and keep up the good work even after everything is over so that you have an awesome, polished game to show off! Good luck!
