Zwackery was an oddity in mid-80s arcades, combining excellent and expressive graphics with surprisingly complex gameplay and controls. Players step into the robes of Zachary Thwacker, a wizard on a quest to save a lovely princess who has been turned into a frog. Along the way you'll encounter crows who love to drop things on your head (and then turn into flying eyeballs), aggressive mushrooms, gargoyles, guards, devils, skeletons and ultimately a dragon, all while trying to defeat the Evil Ghoulum. Zwackery requires near-ambidexterity to master, as you control the wizard with a flight stick with two buttons corresponding to your sword and shield, rotate your sword/shield arm with a spinner, push the spinner down to pick up items and pull it up to cast spells.
We included this game because it's a cult classic, but it is very difficult to play on MAME without a two-button flight stick and a push-pull spinner. If you can find a way to play it, it's something special.
