Arcade Game Designer is a tool for writing your own simple arcade games. While it won't help you create snazzy scrolling shoot-em-ups, it should be capable of producing a variety of basic arcade affairs, puzzlers and platformers so long as you're patient and prepared to stick at it. That is, of course, provided that AGD does not crash horribly or something. Games produced using the utility are stand-alone and can be distributed freely.
The Spectrum version of AGD has already been put to good use by various authors, and is responsible for games like Trooper: point 5, Apulija-13, Donkey Kong Reloaded and Toofy in Fan Land. All four are thoroughly recommended, and can be found in the World of Spectrum archives if you really want to see what AGD can do. The CPC port should be capable of similar things.
Now for the bad news. AGD has its own built-in language, a rather simplistic affair with simple functions and a few built-in variables which you'll have to pick up. In truth the lexicon is quite small, it's mostly a question of understanding how to use each particular command or function. While the program wil l tell you if it finds a word it doesn't understand (although it won't say where), syntax checking is non-existent. Unlike PGD and SEUD, AGD is not quite so user-unfriendly.
Because I wanted to produce a games designer for everyone to use, the program is free to download from my website. Copyright, however, remains with the auth or. Donations are not necessary, so if you really must show your appreciation go out and buy a copy of SEUD or PGD from www.cronosoft.co.uk or something.
AGD comes as you find it, probably containing bugs I haven't yet found. Please do not expect email support - I will be happy to answer questions and hear requests for enhancements and bug fixes on the AGD forums instead. I get around to updates from time to time, other projects and life generally permitting. Until then save your work as often as possible, and preferably as a snapshot if you are using an emulator.
Most importantly of all, have fun. In the meantime, I'm off to Ripley to get hideously drunk.
