I knew I recognized those glyphs from somewhere... burning bright indeed. 🙂
Wonderful little logic puzzle! The hardest difficulty was a bit intimidating at first until I mulled over the logistics of where things would have to be if you are able to travel X-Y steps away. The art is dreadfully fantastic, the music is grim, yet driving (in a sort of "death march" kind of way). I appreciate that digging in the wrong spot just kills you of exhaustion -- it's hard work!
Fantastic! Great work!
