Hello, I stumbled upon this page by pure chance while looking for a game for the English Amiga Board's Guess the screenshot challenge :)
I discovered this game on a Fish Disk back in the mid 90s and didn't get far back then, but found the inclusion of a map editor interesting (always loved editors, and also love top-down games). A few years ago, I started playing the game again in earnest and made maps with all triggers and items. For a PD game, the environments are quite big and it's certainly not your usual arcade affair. Sometimes I wonder what the Marquardt are doing these days ;)
I still have my WinUAE savestate near the final part of the game, maybe I'll finish it someday.
Best of luck with your project!
