One Ball Throw

You are a lone survivor of mankind...

However, there is something else: An alien... more specifically an alien called "Domestic Violence Meatbun Monster"

Defeat the boss by throwing ball at it. The faster the ball hits the boss the more damage it deals.

Controls (available in the game):

WSAD (actually just A and D): Move

Spacebar: Jump

Left Mouse Click: Throw, if you have the ball

Have fun!
