Unlike the majority of Superior Software's BBC Micro games, it was thought that it would not be possible to convert to the Acorn Electron as the game already used up the memory of the BBC Micro and the Electron lacks hardware scrolling capability. After completing the sequel to the game, Martin Edmondson and Nicholas Chamberlain did create an Electron version. The main difference is that instead of one long, scrolling screen, the playing area is broken up into single screen sections. The front end of the game is even more limited than the standard BBC Micro version as the game starts as soon as the game is loaded and there is only a plain screen displaying the score when the player dies. The Electron version was released in 1987 (on cassette only) at the same time as the sequel.
