I loved this one! I also have a soft spot for chameleons thought :P
I agree with some other comments that the hit box is rough -- there were a few times where I triggered a camera even though no pixels were actually touching it. As much as I like pixel art, this is one of the cases where more precise shapes would have been better. This honestly wasn't a big deal though since it just takes you back to a safe spot nearby.
The controls were good and the difficulty ramp was almost perfect for me. A note about using the number keys to change color might be good but it looks like everyone figured that out fairly quickly (it took me a couple of minutes haha).
Overall very nice work!
