Spaceman 8 is a PICO-8 game by kometbomb (Code & Design) and iLKke (Graphics & Sound).
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.
Use the hard-earned credits to upgrade your gear in the shop at the end of each day. How much can you earn in a week? Will you even survive or will greed get the best of you? Only one way to find out!
