A Text Adventure Where You Can Add One Letter to a Choice

'MARY - Rescue Princess Mary' is a text adventure where you set out to rescue Princess Mary, who has been kidnapped by the Demon King.

Its defining feature is that you can add a single letter to the choices that determine the protagonist's actions.

Changing just one letter can send the story in a completely unexpected direction.

You can follow the original path, make things work in your favor, or intentionally create bizarre situations.
With just one letter, you are free to shape your own adventure.

Every story that unfolds is one that belongs to you alone.

Controls

The game is played with a mouse and keyboard.

To choose an option normally, simply click it.

If you'd like to add a letter, move your cursor over a choice and type a single Japanese character.
Press Enter or click the choice to confirm.

The Definitive Edition of the unityroom Version

'MARY - Rescue Princess Mary' began as a game created during a one-week game jam.

The Steam version is the definitive edition, packed with features and story branches that couldn't fit into the original one-week development period.

While preserving the charm of a short, highly replayable adventure, the content has grown to over five times its original size, with new meta elements and even games within the game.

Whether you're playing for the first time or already enjoyed the unityroom version, you'll find plenty of new content to experience.
