Astro Boomerang!
Astro Boomerang! is a souvenir in WarioWare: Twisted! found in the Games section. It is an expansion of the Boomerang! microgame, and features a young boy with a boomerang fighting off a horde of alien invaders. By tiling the console, the boomerang is thrown towards the enemies, with its speed and angle depending on how quickly the console is twisted. The enemies consist of tomatoes that deal no damage and small, screw-like spaceships that line up with the boy's hand before diving towards them. They can be defeated if they are hit by the boomerang If the screw spaceships hit the player just once or if the player fails to catch the boomerang, they automatically receive a Game Over. When an enemy is defeated, it increases the player's score, and defeating multiple enemies in a single throw ticks up a multiplier that increases the gained points per enemy. Occasionally, a power-up appears that can be obtained with the boomerang: this includes a barrier that protects the boomerang from flying away once, a clock that slows down time, and a star that instantly destroys all enemies on-screen. After fighting off enough waves of enemies, a boss appears. It attacks by slowing floating towards the player, defeating them if it touches them. It can survive a few hits from the boomerang, though after enough attacks, its head starts quickly flying around while the rest of its body is destroyed. Once the head is destroyed, the boss is defeated, which restarts the wave of enemies. This repeats until the player loses or quits.
