Jumping Girl is a vertical-platforming action game where you guide a cartoon character upward by timing jumps between moving platforms. The screen scrolls upward continuously, and falling below the bottom edge ends the run. Platforms come in different types: normal, crumbling, spring, and moving. Collect stars for bonus points and shields that absorb one fall. The pastel aesthetic features cloud backgrounds, cheerful character animations, and a relaxing chiptune soundtrack. A weekly challenge generates a unique platform arrangement for global competition.
