Crab Heights

You wake up many years into the future, only to find humans are almost extinct and crabs are now the kings of the planet!  One such crab, Dr. Crabnorg, uses you as his test subject in order to test a jump boost ability that he'd been working on.  However, the power he gave you is defective and only lets you jump a certain number of times before you collapse and need to start over!  Your jump height also decreases each time you jump, so think carefully about when to leap.
