Deep Lift

The deep sea station has broken down without warning and everything has come to a complete standstill. Someone needs to go down there and repair the damage, you are that someone. Under normal conditions such a job would prove no difficulties, but faith has turned against you as your wrench slipped from your hand and plummeted down. You must retrieve it to finish the repairs. Be very careful though, one wrong move and you'll disappear into the deep blue.
