About this game
Terra Probe puts a red mining robot inside caves filled with earth, diamonds and unstable rocks. Each cave specifies a gem quota. Collect enough to open the purple-and-yellow exit, then guide the probe into it.
Digging removes the support beneath rocks, which then fall. That is dangerous to the probe, but a falling rock can also destroy a rival mining droid and create more gems nearby. Crushers, timed explosives and other devices offer additional ways to change the cave.
Use the arrow keys to move. Holding Space with a direction excavates that neighbouring square without moving into it. The instructions inside this build assign F1 to restart, F2 to redefine keys and Escape to quit; these take precedence over the older README's conflicting F1 note. Plan a route before digging beneath a boulder.
