Lennon's Leap: Rhythm Runner

Tap to jump. Hold to hop. Don't stop. Lennon's Leap is a one-touch rhythm auto-runner: your comet races through a neon world where every spike, pit, and jump lands on the beat of the music. One hit and you restart — instantly. The attempt counter remembers everything. You'll be back. SIX LEVELS, ONE DIFFICULTY LADDER From First Flight (easy — learn the rhythm) to Demon Core (abandon hope), each level brings faster speeds, denser obstacles, and its own original soundtrack, from 112 to 152 BPM. MUSIC THAT PLAYS THE LEVEL Every track is generated live in code — driving drums, octave bass, and a melody hook composed for each level. Obstacles are laid out on the beat: when in doubt, jump with the music. MEET THE SCIENTISTS Every level honors a legend of science, with a bio worth reading: the Wright Brothers' first flight, Katherine Johnson's flight-path math, Tesla's electric world, Grace Hopper's nanoseconds, Einstein's speed of light, and the true story behind the Demon Core. Play the level, then meet the genius. EARN YOUR COMET Eight unlockable comet colors — earned by beating levels or by sheer stubbornness. Yes, dying 250 times unlocks one. We see you. Pay once, own everything. No ads, no in-app purchases, no accounts, no internet needed. Just you, the beat, and the next attempt.
