This is a shooting game. There are guns and bullets on your ship. You must eliminate a large number of viruses and avoid their attacks. After you eliminate the virus, you can upgrade your weapon to strengthen your strength. Please cherish the bullet.

The viruses you will encounter have a number on them, this number tells you how many bullets they need to be destroyed. At first, you can only shoot 1 bullet at a time but later you can upgrade your weapon.

Once a virus with a high number is destroyed, it will spawn many more other viruses. You must avoid these viruses to no get hurt. You can also upgrade the value of the gold the viruses drop and also the amount of daily gold you can claim.
