Play the role of the ore man and explore the world from below. Dig through several routes and kill all ants and several deadly creatures from the underworld. The insets will mutate and attack you whenever they find a route. A special technique to kill the insets is by digging the ground such that the rocks fall upon them from above. They will instantly kill the enemy. Another way is to use your firearm. Use the z key to fire towards the enemy and kill all of them to clear the stage. Coming in contact with the insects will reduce your health bar and is it runs out, the game will be over.
