Prototype Review - Super Mario

For my controller prototype, I went for a low fidelity cardboard box so I could actually test out the controllers functionality. The box is designed off of the Mystery Boxes within the game, obviously just made of cardboard and therefore brown rather then yellow. It uses the built in accelerometer for movement inputs, using the X-axis for left and right and the Y-axis for jumping and crouching. The controller also uses an external light sensor, which is allows the player to use the fire flower powerup. While the controller is very visually simplistic right now, does it give the idea of it being specially Mario and not just a brown box? If there were any ways you would improve it, what would you do?

Two Notes: 1) I know its a small mess of wires, but it's functional. 2) I stated it in the video, but the controls are a bit sensitive and don't always fully work as intended, I want to adjust them.
