Written by Swedish author Lars-Henrik Lindahl. There are two versions of this game archived. One is text-only. The other has illustrations; probably utilising Bo Jangeborg's QPE/GRAX graphics hack (code which was later developed into routines to power Bo's The Artist and Fairlight).
An unofficial conversion of the text-only ZX Spectrum version is available for Atari 400/800; ported by devwebcl.
Not very original...
