About this game

Prism Bastion is a gothic tower defense where you place crystal towers along a winding path to stop waves of shades, wraiths, golems and bosses before they reach the Crystalline Sanctum. Spend earned crystals on four tower types that beam, slow, splash or reveal cloaked foes, and between waves crack Caesar-cipher puzzles for bonus crystals. Hold out as long as your twenty lives allow against ever-tougher waves.
