Hardly unique. It might be cool if you could turn things into different QR codes, but this is just one particular code turned into a map. Even level 2 uses the same map! As others have pointed out, the design itself is very inconvenient, often leaving the level impossible. Beating level 1 is a matter of dividing your lives into 'runs' where you plan to take on a certain area of the map and leave the powerups immediately accessible. In this game's defense, the trickiness does make it addicting, and the game engine works surprisingly well. However there are definite oversights such as ghosts spawning on top of you.
Needs serious improvement.
