The Incredible Crash Dummies

You play a crash test dummy, trying to progress through levels filled with hazards such as cars and fireballs, within the time limits. Contact with each of these loses you a limb, and once you have none left, contact means game over. Since the character isn’t handicapped by missing limbs in any way, in practical terms you can think of these as hit points especially as there are screwdrivers to pick up which restore one limb.
