Blastronaut is a space procedurally generated resource gathering sci-fi game. Use your blue goo gun and jetpack to break apart blocks on the planet and find precious resources. Upgrade your machines in order to buy fuel and other abilities and tools.
I played the beta demo in Steam and never saw a SteamPlay warning... so I'm not sure if it was a native version or not? But either way, the game played beautifully! I was able to maneuver with my jetpack and dig down into the planet to find the best resources. Be careful not to waste your fuel... otherwise you might not make it back to the surface.
