SoundLeap · A Voice-Controlled Platform Adventure

Why voice

The run is automatic. The rhythm is yours.

SoundLeap is an original side-scrolling runner. Your character keeps moving while voice volume shapes every jump: use a soft sound for a stone, speak louder for a gap, and go quiet to let the runner land.

The microphone is not the only way in. The Space key and touch input use the same continuous jump model, so the full game remains playable without a microphone or when permission is denied.

Three campaign acts gradually increase speed, obstacle density, and enemy combinations. Endless mode streams new terrain into one continuous scene while preserving health and score.

One jump, three decisions

Make a sound

The browser reads live volume only, never speech content. A soft sound makes a short hop; more volume adds upward force.

Leave space

Go quiet and allow the runner to fall. The challenge is not constant volume but leaving enough room for a clean landing.

Find the next beat

Jump again after landing. Coin trails, echoes, and enemy patrols all hint at the timing of your next sound.

Three-act journey

Every act changes the way you use your voice.

01Windlisten MeadowLearn to let your voice landWide platforms and readable coin trails teach small leaps, high jumps, quiet landings, and safe stump tops.→02Echoing MistwoodConnected gaps disturb your breathDenser obstacles and roaming enemies shorten reaction time and ask you to recover your rhythm between jumps.→03Starfall GorgeKeep precision after speed arrivesShorter platforms, wider gaps, and faster enemies form the final test. Steady timing matters more than constant volume.→

Your voice stays on your device

The game needs volume, not a recording.

Microphone audio is analyzed immediately in the current browser through the Web Audio API. Raw audio is never uploaded or saved; volume exists only as a temporary control signal.

No speech recognition
No raw audio upload
