Cosmic Wartoad is an action game developed by Denton Designs for the ZX Spectrum.

[1][2] The queen of the cosmic wartoads has been kidnapped by the Rygellian Slime Beasts, turned into a human and is being held captive beneath the Slime King's Sludge Saw, which descends over the course of ninety minutes and will kill her if it is not stopped.

Each node contains one of several repeating minigames, which typically involve the Cosmic Wartoad fighting enemies.

The game finishes either when the Cosmic Wartoad successfully collects all eight pieces of the Toolkit and navigates his way across the grid to shut down the saw; when the Cosmic Wartoad loses all of his three lives; or when the ninety-minute game period expires.

It was designed and drawn by Steve Cain, with code provided by John Gibson.
