Buy Voice of the Wizard by Brett Farkas Cheaper!

The game is now free since the voice recognition capabilities suffer from false positives. Nevertheless, it is an interesting early example of voice recognition gaming, so I am leaving the game up. Touch control versions of the game without any voice control are available for free on mobile IOS and Android.

Voice of the Wizard is a 100% voice recognition controlled adventure game.
It features bright pixel art graphics in a 42 screen overworld map. Including hidden areas, there are 115 backgrounds total.
You are free to traverse an open world. Learn magic spells along the way and cast them using your own voice. Roam an island, encountering witches, knights, warlocks, ogres, and centaurs.
It is up to the little blue Wizard to discover the circumstances of his imprisonment. A mysterious castle looms in the center of the island. Mermaids sing idly by the seashore. Fairies flit about with their secrets held close. Explore and discover hidden adventures in the tropical island. As the Wizard learns new spells he comes to new realizations about his circumstances, and unlocks new areas.
Discover the secrets. Solve the mysteries. Defeat your enemies. You will be the Voice of the Wizard!
