Gemsweeper
Carefully excavate a crumbling mine in search of gems, energy, and framing materials. Use arrow keys or WASD to move around and excavate.
The core mechanic is that each soil type contributes a different, slightly random amount of strength to both its row and column. If the strength of a column or row ever drops too low, the entire mine collapses and it is game over.
Green gems are the scoring currency. Pink bolts give energy, which is constantly decreasing while moving and even more so when excavating. Orange framing materials let you automatically shore up an area that would otherwise cause a collapse.
