I really enjoyed the game. Great idea! Although it was hard to control at first, I got used to it pretty quickly. Clever use of the color pallet as well. I had a couple of glitches with bigfoot spinning around or just stopping randomly, but not that many of them. I also got stuck on some invisible walls a few times, but only for a few seconds. When I was chasing bigfoot I looked on my phone and even though I could hear him, I thanks to the colors had no idea where he was. Elusive indeed. It would be nice to have the trees as a solid objects so you would have to pilot the drone much more carefully. Also it would be great if the drone would start on the ground, That way you have more time to look at controls before it plummets to its death :D Very nice easter egg. Btw when I heard bigfoot for the first time I couldn't see him. It scared me so much having no Idea what it was :D The idea of keeping photos is cool as well. It would be great if you could at least choose a photo for the newspaper.
Overall even with a few issues I really enjoyed it. Great work!
