Mr. Wiz is a single-player casual and arcade game in which players control a wizard navigating a garden environment. The core mechanics involve guiding the wizard to eat cherries while avoiding or defeating evil gremlins using a crystal ball or by causing apples to fall on them. In this game, the setting is a whimsical garden where the wizard must strategically avoid gremlins that can be killed or distracted through specific actions, with bonus points awarded for eating magic mushrooms that temporarily enrage the enemies. It stands out with its simplified enemy interactions compared to similar arcade titles, focusing solely on gremlins without other monsters, and features unique gameplay elements such as making apples fall and the risk of gremlins digging passages or eating apples when frustrated.
