About

RhythmJunction

Features
Read full description

Rhythm Junction is a 4-lane rhythm game with a twist: at every junction, you choose your path. Tap, hold and hit chords to the beat. When a junction section arrives, two doors appear on either side of the screen. Turn your head slightly left or right and the front camera reads which way you are facing — pick the hard path for a higher score or the safe path to protect your combo. A touch fallback is available for situations where face tracking is not convenient. FEATURES • 4-lane rhythm play with TAP, HOLD and simultaneous notes • Branching charts — the same song plays differently every time you choose a different path • 24 songs across electronic, house, rock and running beats, each with 3 difficulty levels • Judgments, combo, rank and best records saved per song • Online rankings — compete with players worldwide per song and difficulty • Achievement rewards — earn POINT for S+ ranks and perfect runs • 30-day attendance calendar — 50 POINT every day, a Golden Key on day 30, and a 150 POINT bonus for clearing 3 songs in a day • Unlock locked songs with POINT — every song can be unlocked just by playing • Fine calibration for audio, input and display offsets Play right away as a guest, no sign-in required. Sign in with Apple, Kakao or Naver to save your records to the server and use online rankings and the POINT shop. Face tracking runs entirely on your device. No video is stored or transmitted. No ads. POINT can also be purchased in-app (optional).
