Power Plane is a special item that becomes available after reaching level 291.
To activate the Power Plane, you need to beat 10 levels. The Power Plane stays active until you fail a level. If you fail, the Power Plane will reset, and you'll have to beat 10 levels to activate it again.
The Power Plane is a chargeable special item. You can charge it by exploding power-ups! When it's fully charged, three Power Planes are released, and they remove 3 random obstacles to help you reach your level goal!
