“Thrust Harder”, by the Kranzky Brothers, published by Arsepipe Productions. The Kranzky Brothers are Lloyd Kranzky (programmer), Keith Kranzky (graphics) and Brian Kranzky (sound effects and music).
The game is a mashup of Thrust, Exile, Mercenary and so forth. You can run around as a little spaceman, in which case you use keyboard to move and mouse to aim and shoot. You can drive a land vehicle, or board a spacecraft to fly around. A little economy based on ore, destructive objects, HP and XP all over the shop, updrades and levelling, a drive to explore, a rescue mission to find all colonists.
