Flutterjump: Performed by holding Jump in the air.
Shield: Performed by holding Special. Creates a frontal barrier that can deflect attacks and damage enemies.
Burst: Performed by releasing Special after a Shield.
Phantom Block: Performed by holding Attack for a certain amount of time. The cube itself and the sparkling formation of a cube both function as a raised shield, and can deflect attacks. Shield Crystals, bombs, Flower Pods can be lifted to replace the Phantom Block if Milla approaches them while holding or forming a block.
Toss: Performed by pressing the attack button while holding a Phantom Block or any other object.
Super Shield: Performed by holding Special while holding a Phantom Block. The block creates a LARGE frontal shield with better coverage.
Super Shield Burst: Performed by releasing Special after a Shield. This attack deals good damage at a longer range than the other girls can reach AND the entire duration of the attack also counts as a projectile-deflecting barrier. Best of all, using this gives Milla an immediate burst of speed.
Super Shield Boost: Releasing a downwards-diagonal SSBurst immediately after jumping gives Milla a huge boost of speed from recoil. She will quickly lose that speed if she is gaining height, but if she is falling (for example, by hitting a ceiling during the SSBoost) she can KEEP the speed and even follow it up with another SSBoost! When falling after a short hop, or shortly after Milla has run off of a platform, using a horizontal SSBurst will still allow her to keep the recoil boost of speed. The trick is to release the the SSBurst as soon as possible after initiating the jump or beginning to fall to prevent Jumping Air Drag.
Air Drag: If the player character is moving upwards, their horizontal velocity will decay. This general rule applies to all characters, but is particularlly noticible from the harsh slowdown after one or two good SSBoosts with no ceiling.
Flutterblocking: If Milla is falling when she performs a Super Shield Burst (for example, just after hitting a ceiling, or when doing the burst in one of the Jade Creek drops) she can start forming a new Phantom Block as soon as the Super Shield Burst animation ends. However, the player presses and holds Attack and Jump at almost the same time when the conditions to make a new Cube is available, Milla will begin to Flutterjump while creating a new Phantom Block.
Demonstrated above: If care is taken such that each SSBoost is only performed while Milla is FALLING, it is possible for her to chain several Flutterblocks together. It looks cool, it makes certain bosses easier, and it can be used to save herself if she’s falling in one of the few levels that has a death pit.
