Quark is a Boulder Dash clone with more features, Supaplex's techno
aesthetic, and a soundtrack comprised of oldskool tracker music. It
also includes a level editor. In version 2.1, Quark was renamed to
Hadron. This game is not to be confused with [Quark (Spencer
Seidel)][1], nor [QuarkXPress][2].

Arizona Software's websites are gone, but the game is still
downloadable from the Wayback Machine: [curvuspro.ch][3], [arizona-
software.ch][4].

Softlock glitch in Hadron 2.1 for Classic Macs: In Level 21, if you
use a checkpoint and then die, you can't use the two tubes encountered
shortly after the marble hallway. You must restart from the beginning
of the level.
