High potential
This game has a really high comedic value. It gave me the same feeling as Smash TV does, a quirky bodily harming gameshow.
Also, there is a lot of potential, the idea of prosthetic limbs, the shoes giving you a little speed, that sort of thing. Maybe having a different arena every 5 questions would be cool, each stage has its own set of hazards.
Points off for lack of customization left to the player (speed/defense?) and its kind of linear, once you are there, thats it. Good job, good idea, flesh it out a little more.
