Click on the screen to move Grimace right to avoid the Skibidi Aliens. Flick upwards to launch snowballs at the aliens to block their advance. Monitor the shakes at the top of the screen; if the aliens get to them, the game ends. Pick up power-ups that appear randomly to improve Grimace's abilities, such as raising snowball speed or granting temporary invincibility. Survive as long as possible to earn high points and unlock new levels. Modify your strategy based on the escalating speed and number of aliens to keep your defense.
