Airball is a cancelled action game / puzzle that was in development by Novotrade and it would have been published by Tengen for the NES. As we can read at Lost Levels:
the game itself is a pseudo-3D isometric fetch-quest, along the lines of Knight Lore, Alien 8, Batman and the like (or, if you’re only console literate, Solstice on the NES). As the NES-exclusive opening cinema shows, an evil wizard has turned the player’s human character into a ball, and sets him on a journey around his castle to find a handful of items he’s misplaced.
The project was lost untill a prototype was found again in 2007: thanks to Retro Zone you can buy the reproduction of the prototype and play it on your NES console. (It works on authentic Nintendo Systems including NTSC, PAL A, PAL B, and Asian systems!)
Thanks a lot to NES World for these screenshots!
