Mandelball
Roll around the Mandelbrot set!
As the ball gets smaller, the distance it rolls around the perimeter increases, approaching infinity. The smallest size allowed in the game is 10-6. At that scale, if you were the ball, the Mandelbrot set would be approximately the size of North America!
Use the left/right arrow keys to roll, and the up/down arrow keys to grow/shrink. Press space to jump. On a touchscreen, hold your finger on the right side of the screen to roll clockwise, and the left to roll counterclockwise. (So if the ball is rolling upside down, touching right actually makes it move left.) Pinch to grow/shrink. Tap to jump.
There are 64 coins hidden throughout the fractal at different sizes. You'll need to shrink to enter swirly passages and endless spirals! Every 10 coins unlocks a new color. Look for the coins near places with interesting and unique patterns. Can you find them all?
