DeepVent

The sand at the bottom is soft and safe — rest there. Everything above it is bare rock. Up the vent, through the spiked turn at the top, then down, across, over the hump and down again into the chamber. Whatever is down there, you are not coming back out.

SpaceOne puff per press, one bubble each. Holding it does nothing — you have to tap.
←→Steer. Scraping bare rock costs a bubble, so keep off the walls.
5 bubblesEach one comes back 3 seconds after you spend it.
