About the studio

Mystical Door Productions is Hal Knight's studio for Android games and apps.

Its first game is The Mystical Door, a fully voiced, turn-based story RPG in four books, now in closed testing on Google Play. Next is Whimbrel, voice typing that works without a connection, now in development.

How we make them

• Nothing is tracked. Our games, apps and websites show no ads and use no analytics or trackers.
• What is yours stays on your phone. The Mystical Door keeps your saved games on your device, and Whimbrel is built to turn speech into text on the phone itself, so the audio never leaves it.
• Each product gets its own Help Center, with answers, patch notes and a way to reach us.
