The player's primary power-ups are bells that can be uncovered by shooting at the floating clouds where they're hidden. If the player continues shooting the bell after it appears, it will change into one of four other colors: the regular yellow bells only grant bonus points, the white bell will upgrade the player's gun into a twin cannon, the blue bell increases the player's speed (for up to five speed levels), the green bell will allow the player to create image copies of its ship for additional firepower, and the red bell will provide the player's ship a barrier that allows it to sustain more damage. The green and red bells cannot be combined together. Other power-ups can also be retrieved from ground enemies such as an alternate bell that gives the player's ship a three-way gun, a star which eliminates all on-screen enemies.
