Control your Xyloxi character with the arrow or WASD keys. Pick up crystal cores while avoiding the Mithri leeches - if a leech touches the Xyloxi, it loses 1 heart.
Cores come in 3 colors, each providing your with a small bonus. Red cores launch a homing missile at the nearest leech, blue cores shield you from leech damage for a short time and yellow cores increase your speed for a short time.
Every 10th core you collect provides an additional bonus. The 10th red core launches a large number of missiles, every 10th blue core heals your Xyloxi for 1 heart and every 10th yellow core slows down all enemies for a short while.
In some missions, crystal towers will aid you against the Mithri - these towers fire missiles periodically, but they require energy to do so. Collecting crystal cores will charge the tower of the same color - each core allows a tower to fire 3 missiles.
Six mission types are available, each in 3 difficulties : Collect, Survive, Charge, Swarm, Endless and Boss.
