The main character of this game is Headdy, a puppet-type creature that is able to detach and use his head to accomplish various tasks needed inside of the game's world. At the beginning of the game, Headdy arrives in a small town and discovers that King Dark Demon is trying to turn all of the inhabitants (puppets and toys) into a legion of evil minions. Headdy is captured by the king's workers, determined to be unworthy of becoming part of the evil team, and is put into a cargo ship bound for the incinerator. Luckily, he escapes, which brings us to the beginning of game play and the motive for the game. The player, controlling Headdy, must play through a series of scenes (in a landscape that looks similar to early Sonic games) ending, usually in a battle against on of the Keymaster bosses. In total there are 9 stages, each with numerous scenes and bosses to defeat. Killing the Keymasters helps the player progress in the game, and collect pieces of keys to help unlock levels at the end of the game. The player is also able to unlock bonus codes in each level by achieving certain tasks like killing a certain enemy, or destroying objects in the terrain. There is also, thankfully, a level select option—this isn't a short game, and starting from scratch would probably be pretty frustrating.
Along with the pretty basic plot, but amazing mechanics, Dynamite Headdy sported a sense of humor that, while I didn't understand it at the time, is now very appealing to me. Many of the section titles are punny references to popular movies at the time—you can see some here:
- Toyz 'n the Hood is a pun on the movie Boyz 'n the Hood
- Clothes Encounters is a pun on Close Encounters of the Third Kind
- Terminate Her Too is a pun on Terminator 2, the second movie in the Terminator series.
- Stair Wars is a pun on the series Star Wars
- Spinderella is a pun on the Disney classic Cinderella
- Fly Hard and Fly Hard 2 are puns on the movies Die Hard and its sequel.
- Headdy Wonderland is a pun on the book Alice in Wonderland
- Illegal Weapon 3 is a pun on the movie Lethal Weapon 3
