Be a Space Spelunker!

Life has been tough on mining colony w4ge-514v3, but you are tougher. Don the helmet of Spaceman 8 and mine the labyrinthine busom of icy spacerocks for gems and haul them back to company collectors. The oxygen supply is scarce and depleting fast, so you have to keep your visits brief. Luckily, your trusty hummingbird-class jetpack is highly manouverable, and will get you to the exit quickly.
