One Input Worlds

Instructions

Build a browser experience controlled by exactly one input dimension. Your world can be a game, a story, a toy, a ritual, or something we have not named yet — but the player may only use ONE continuous control: scroll position, mouse X or Y, a single key held or tapped, device tilt, or another single-axis input you declare up front. Hard rules: - No menus, buttons, or multi-key gameplay (modifier keys count as extra inputs). - No text fields or forms — if words appear, they must emerge from the input itself. - Must run in a modern browser without installs. - Must be completable or meaningfully explorable in under 5 minutes. What we are looking for: - Constraint fidelity — does it truly live on one input? - Expressiveness — does that one gesture carry emotion, surprise, or mastery? - Craft — visuals, sound, pacing, performance. - Replayability — worth a second pass? Declare your chosen input in your entry title or description. Push the constraint until it sings.
