Lone Spaceship You are a Lone Spaceship in space and you are lost trying to explore the empty void. The main concept of this game is to shoot asteroids to get the crystals(ammo) that will be inside the asteroids and you need to collect those Crystals(ammo) to be able to get special bullets to kill the boss, But you must find the boss somewhere in the map in order to kill it. You press spacebar to shoot regular ammo to destroy the asteroids, Z to shoot the special bullets to harm the boss, and the arrow keys to move the spaceship.
