Pretty good game overall, I'd say. I like the way you implemented the theme! The art style was interesting. Good, that is. The music was a bit underwhelming, but still fit in pretty nicely with the theme whereas the sound effect were pretty pleasing.
I found it a bit strange that a line of dots were being drawn out as I walked around. In any case it gave a good bit of feedback, but maybe that's just the SFX.
The level design made the gameplay fun and intriguing, though some were a bit rage-inducing as well. I'd suggest adding a sort of timer to being detected by the cameras to make it less of a death sentence to take a wrong step. Which brings me to the controls. They were good, but it was a bit hard to stay away from the "detection zones" when I could only move in 8 directions in a very short time-span. Maybe using the mouse to move would have been better? I don't actually know, that's for you to try out.
