About

Rockford navigates underground caves collecting diamonds while dodging hazards in this 1984 puzzle game. Players dig through soil, push rocks to block or crush enemies, and time their moves carefully. Fireflies and amoebas attack on contact, but dropping rocks on them turns them into collectible gems. Each cave requires gathering a set number of diamonds to unlock the exit, with shifting terrain and crumbling rocks adding tension. Progress through 16 caves across five difficulty tiers, with logical intermission puzzles breaking up the action after every fourth level. The game’s tight physics engine and risk-reward design keep each level tense. Rocks fall and slide predictably, demanding precise planning. Though built for the Commodore 64, its mechanics hold up as a pure test of spatial reasoning. Over 40 years later it remains a benchmark for puzzle logic, with retro fans praising its unflinching difficulty curve. No hand-holding, just 16 caves of escalating cleverness.
