Mostelix

A minecart descent. The speed is controlled by holding to brake and releasing to boost, carrying the cart through curves and over gaps without flying off the rails. Reading the track ahead is everything: too fast into a curve throws the cart, too slow into a gap drops it short. Thirty tracks raise the pace, tighten the curves, add gaps to clear at the right speed, and branch the rails on the later runs. A track is cleared by reaching its end on the rails.
