Chex Quest

Set on a distant planet named Bazoik, the game follows the Chex Warrior, a soldier clad in a Chex-shaped suit of armor, as he eradicates the invasion of the planet by the 'Flemoids': a species of slimy, green invertebrates, who have infested the planet and captured many helpless colonists, whom the Chex Warrior must save. His main weapons are devices called "zorchers", which teleports his enemies to their home dimension. (wiki)
