Throughout the stages, you'll encounter small, colored spheres that act as 'level-up' items for your characters. Collecting these spheres enhances the abilities of the character currently leading your team. There are three types of spheres, corresponding to the three character types:
- Red Spheres (Speed): Collecting these levels up your Speed character. This increases the power and range of their Homing Attack, making them more effective in combat.
- Yellow Spheres (Fly): Collecting these levels up your Fly character. This increases the duration of their flight ability and the power of their Thunder Shoot.
- Blue Spheres (Power): Collecting these levels up your Power character. This increases the power and area of effect of their attacks, making them better at breaking obstacles and clearing groups of enemies.
Each character type can be leveled up a maximum of three times (Level 1 to Level 3). The effects are cumulative and last for the duration of the stage. Prioritize collecting these spheres, especially for the character type you use most frequently or for specific challenges. For example, if a stage has many flying enemies, leveling up your Fly character will make it significantly easier. These level-ups are crucial for maximizing your team's potential and achieving higher ranks.
