Scorecard
A clean landing means your trajectory angle matches the hill.
Ready to ride
Press Launch to fly. Match your landing angle to the slope for a clean landing.
Distance: — m
Trajectory ∠: —
Hill ∠: —
Mismatch: —
The mismatch (how far your landing angle misses the slope) is the score that decides the outcome: ≤6° clean, ≤12° wobble, ≤19° tumble, more than 19° crash. Same physics engine as the lesson — this just draws a game on top.
