Ball Jumper

A hyper-casual vertical platformer about an unexpected pair stuck in one body: Red and Blue. You can't pick who you are, you have to crash to become each other.

Bounce upward, dodge your own wrong color, and sacrifice height to swap at the perfect moment. Chase your best height, one dive at a time.

How to Play

• DRAG left / right: steer mid-air. Slip off one edge, appear on the other.
• TAP: dash downward. While dashing, every platform is solid, and touching any of them swaps you Red ↔ Blue.
• Auto-jump: land on your own color (or neutral green) to bounce.
• Wrong color = ghost platform, fall right through it. Unless you're dashing.
• Don't fall below the screen. The camera follows you all the way down. (Yes, like Doodle Jump.)

The golden rule: to go UP, you must first dive DOWN.

Why "Unexpected Pair"?

• Red & Blue share one body. They're rivals forced to cooperate, only one can exist at a time and switching means literally slamming into the world.
• Swapping is never free. Unlike most swap mechanics, every color change costs height. Each dive is a gamble: convert now, or hunt for a green platform?
• Green is the third wheel. The neutral mediator both rivals can always trust.
• An inverted moveset. In a genre about climbing, your most important button points down.
