From what I COULD play, I have this to say:
- Can run through walls making camera flip around when you go into blank space.
- Doors should open outwards and not into character.
- Getting past the first guy and hitting the steps makes the camera go out of control.

So far, the game isn't playable. As far as the game mechanic, just avoiding stationary light cones doesn't seem very fun and I wouldn't rate very high for the game even if it was all fixed up.

Screen is really shaky; hard to look at.

As others have said, there is a serious problem with the camera. Just going up a few steps can offset it enough that it flips the entire level over or worse, flip the cube onto its side to where the up arrow key will make it jump. It is possible to flip back to normal through messing with. I'd suggest putting a lock on the z-axis of the camera. The only time the camera really needs to move on that particular axis is when you fall down a pit (though I do like the fact that it looked like it switched to a first person view when I was falling). Although you included a feature to fix the problem in the game, the fact that the player must actively fix it makes it hard for the player to get engrossed in the game and just makes they ams look unprofessional.

You should also have some kind of indication that the enemy has seen you or is about to see you because I can still get partially touched by their lights without restarting (you can have the light begin to turn level when it's getting to the point that you will get caught).

Still, I look forward to see what you have to offer in this in the future.

camera is super buggy. i kind of like it. is the trigger door the ending?

If you could make the player cube not flip on the side with the camera every time you try to move, that would be great...
