As far as I know, the game was never released in any form. In fact, it was probably never finished. (But please tell me if you know otherwise!) I recently found a copy on an old floppy disc and, although I've lost touch with the original author, I cheekily went and ported it to Graphic Adventure Creator, debugged it, completed it, and added some intro screens -- mainly so that I could amuse myself by writing silly programs in BASIC, but also because I realised I could now play around in GAC without having to come up with story- and puzzle-ideas of my own! (Lazy, I know.)
Alien Jailbreak isn't a very big game. (Mind you, it'd be even smaller if it weren't for that dratted maze, and if it weren't so "Nasty". (Look, it was the 80s... and anyway, I've included a full spoilery map in the zip file with the disc image.) Also, I think the game's short because it was originally intended to be Part 1 of a series -- ambitious!)
Nor is Alien Jailbreak the most ingenious or exciting text adventure in the world, but I thought that the original author's design was good enough to be worth finishing. The game is now complete and winnable. Please let me know if you try it and have any comments.
(Btw, grackle dumps were a great help when I started debugging the original Alien Jailbreak game data file. Thanks, tautology.)
