Knock Twice

Six doors. Every house has its own way of saying come in. At midnight, a seventh door appears. A rhythm mystery with two endings, made for Bound Jam 2026 — Expect the Unexpected.

How to play

• Choose a door and knock its rhythm. A short gap is about 0.5 seconds, a long gap about 1 second.
• Press Listen to hear the rhythm again. The light also blinks, so you can play with sound off.
• Visit all six houses to open the seventh door and reach an ending.
• Sound turns audio on and off. Restart starts over.

Plays in Chrome or Edge. No installation needed.
