Kristanix Games has released Zamby and the Mystical Crystals (US$19.95), a new fantasy puzzle game for Mac OS X. The goal of this non-violent game is to use logic, stealth, guile, and imagination to guide Zamby through a wondrous world of light crystals, monsters, and obstacles. Like all Qwonks, Zamby needs light crystals to illuminate his underground cave. He sets out to explore his vast world, and collect as many crystals as possible. In addition to the huge library of puzzle levels, the program’s built-in level editor lets you build your own challenges.
