Two pedals, forward and back, and a vehicle with suspension that has opinions. The course is a side on obstacle run of ramps, seesaws, spinning bars and drops, and the physics are the whole difficulty: too much throttle and the nose comes up, too little and you stall halfway up a slope and roll back into the last thing you cleared.
Levels are short and restarts are instant, which is the correct arrangement for a game where you will fail the same jump eleven times and clear it on the twelfth without being able to say what you did differently. It gets hard quickly and it stays fair, and the moment a level clicks it goes from impossible to routine in a single attempt.
