About the Game

Once upon a time, a nefarious necromancer summoned an army of vengeful spirits to wreak havoc upon the world. Unfortunately, they only wanted to wreak havoc upon HIM! Now he must undo what he has done by drawing upon the power of magic sigils to blast the ghouls back to the netherworld. Featuring an innovative mix of color matching puzzle mechanics and fast-paced, twin stick shooter action.

Features:

  • Addictive Puzzle/Shooting Gameplay: Highlight colored sigils to match the approaching ghouls, build up your magic charge, aim, and fire! Also, try not to die.
  • Story Mode: Fight through 10 levels across multiple environments, including Swamps, Graveyards, Badlands, and the dreaded Tower of Chaos!
  • Arcade Mode: Survive as long as possible against ever larger waves of ghouls. Choose from 10 different arenas and rack up high scores in endless, arcade-style gameplay.
  • Power Ups: Grab special weapon boosts to increase your firepower. Slice through enemies with spinning blade attacks, or fire straight through barriers with an unstoppable beam of magic.
