The Tortoise and the Mario

Level Title: The Hare and the Mario

ID: 4024-0000-0040-6410

Description of Gameplay Elements: Pretty much a race between the tortoise (Buzzy Beetle) and Mario. Mario lands on the Buzzy Beetle, the beetle becomes a shell and begins to go across the screen, and Mario overcomes to obstacles in place to make it to the end before the shell does.

I would love some input as far as how to make this a better stage. I originally wanted to have the shell bounce on a P switch so that it would prevent Mario from reaching the end but it I can't rest the P switch horizontally. I was also hoping to have a Thwomp land on the switch but it only comes down when Mario is near, not the shell. My last note is that someone could also choose to come down fast on the shell or grab it, therefore making the whole race aspect irrelevant. Anyone got any ideas/suggestions to make it better? What do you think? Thanks and all that good stuff.
