You will control a bullet that moves at breakneck speed and destroys everything in its path. Many opponents and obstacles will stand in your way, including Mario, Luigi, Goombas, brick walls, tunnels, rocks, and more. To avoid collisions and collect useful items like coins, jewels, and bombs, you need to move fast. You will be able to fly around four different worlds, and you will be able to meet a lot of new people.
You can easily control your character with the mouse in Bullet Bill. Drag the mouse or touch device on the screen to move up, down, left, or right. By moving the mouse left or right, the speed can be increased or decreased. The spacebar can also be used to pause the game.
