About

Perlin Ball

Features
Read full description

Perlin Ball is a simple but challenging game of guiding a ball along a narrow course toward the end goal. You do not control the ball directly. Instead, you must pivot the bumpy course to move the ball along its path. The sloped course is created from mathematically-generated Perlin noise and can be tricky to navigate. Try to gain speed and move over the hills to get the best time. Do not lose control, though, or the ball will go flying off the side of the course. Unlock all 6 distances and try to get ever faster times, or try the endurance mode and see how far down you can get.
