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. You can spin around quickly, and it supports rapid fire.
At the beginning of the game, you can select your start level from 1 to 15 (which is how many pit designs there are). If you make it past that, the pits repeat, but their color changes (red for level 16 and up), and it becomes much harder. An early Rainbow Pipelines column says that Computerware said that the game as 135 levels of play total.
