Daunting puzzle game, and it's extremely difficult and satisfying in my opinion. Love the visuals and effects, though the fisheye gets a little tiresome. You deserve a vid playthrough because of how many you upload on demo days. You might as well watch this at 2x speed because I've never felt this brainlet in my life. I didn't understand how blue squares worked until I was deep into one of the later puzzles. Also note I started recording in the middle of my progress on (I believe) the 3rd puzzle.
I have to agree with a point rokas made, I don't like that black on the map indicates both unseen areas and normal ground. Also reading these comments I see there is an undo button I missed... oops. Enjoy this mess of a video, as I enjoyed your game quite a bit.
