Collect Power-Up Items of the same color continuously to increase your ship's endurance and raise the level of your attack. Collecting a Power-Up Item of a different color will change your weapon, so the level of your attack will not rise.

When you collect a Power-Up Item, your Super Shell Stock on the bottom-right of the screen will increase. You can hold up to 3 Stock. You can use Stock whenever you want by pressing the Button. The effect of the Super Shell depends on the color. No matter what the color, you are invincible while using one.

Only the Cluster Power-Up Item will appear.

When you collect this Item when at full-power, it will not have a Super Shell, Gunbody, or Burst Out effect, but will give you additional bonus points.
