The Coveted Mirror

Main character is caught by the enemy and starts in prison. He needs to break free and explore Japanese castle to find five pieces of the mystery mirror within time limit.

The once placid medival village of Starbury groans under the iron-fisted rule of the black-hearted, squinty-eyed King Voar. The dazzling Mirror that the wizard Munjistan once used to protect Starbury is now broken into five pieces, of which Voar the Vermin has four. The power of the whole mirror is absolute, and the tyrant will stop at nothing to find the missing piece. However, should a champion find it first, Voar's power can be broken. Champions are scarce these days, for Voar is virtually omniscient, able to spy on his enemies at all times. You may not aspire to being a champion, but your first meeting with Voar will change that. Do you have the ingenuity to find the Coveted Mirror?
