Did you ever player a roller coaster game in a colorful world? You dont need to move your cart here, just slide left or right and change the color of the roller ball in order to collect colorful dice. Dice are only collectible if the roller ball has the same color.
You can have new roads when you leveled up, and you can get new roller balls with dice.
When you need to relax, you can always switch to Zen mode.
