So interesting concept! I didn't get it at my first try, but once I undertood I found it very cool. Congratultions for the game!
So cool that a path from the knight to the chest is always possible and that the game can detect when you're making "impossible" paths!
I've observed a thing that I don't know if it is a bug or a feature. I've played the web version.When I move around the maze I am building, my "character" (the box with eyes) erases tiles when moving above them :( So I couldn't move the camera to see how the knight was doing.
