Storm is clone of the arcade game Tempest. As with some of Computerware's other early Coco efforts, it used the Semigraphics-24 graphics mode in order to get 9 colors on the screen at once, even thought it had a really weird resolution (64x192). This was ironic since the original used an extremely hi-res wire-frame color vector graphics system. Even with that going against it, though, the game play is similar to the arcade hit, where one spins around the outside of different shaped pits, and has to shoot all of creatures coming from the depths before they climb to the surface and kill you. On simpler levels, you can spin around the entire thing repeatedly, but on later levels (like level 2 shown above), you can only go so far in each direction, and then have to backtrack. You can only move on the outside of the pit.
