You are a hero summoned by your king to fight a demon lord who has taken your princess. Or so it should be, but that story of Hero fights Demon Lord to rescue Princess is suddenly torn apart by the world breaking, due to a mysterious top-hatted individual known as The Puppeteer. He has decided that he can tell a better story and is trying to destroy this one to replace it with his own.
So, to fix the world, you must become a party with Princess Glynn and Demon Lord Volza to set the world right.
This game provides examples of:
- Adam Smith Hates Your Guts: Landia's inn costs 20G, Garmuldar's inn costs 50G, while Duneport's costs 35G, and the former is only slightly further away than the latter, though, the former is a city, while the latter is a port, so it may be Justifed.
- All Deserts Have Cacti: The desert map has cacti and the Racket Cactuses monsters.
- All in a Row: How the party travels, with the order going: Hero, Demon Lord, Princess.
- Blade Spam: Attacking with the Hawk Dagger makes it hit twice.
- Blob Monster: Presumably Oozies and their Underground Monkey variants, given how they appear to be based on ooze.
- Book Ends: In all versions, player movement of the character starts in the Demon Lord's castle, which is where the last bit of player-controlled movement is too, at least in the original, where trying leaving gets a message of, with the second line only happening at the beginning:Determined to bring the Demon Lord to his end, [Character Name] marched straight back into the castle and sought out the throne room!
Look, I don't like this, either. But you're here now, so...
