Magic Pockets, music by Richard Joseph (although somewhat originating with Betty Boo). I've met him a few times (and come to think of it I have a photo of him with me on my site). As for playing it, that voice is a bit too high even for me!
[chat] unfortunately, the innernet has been particularly unreliable this last five days or so, which has been highly frustrating -- so don't be surprised if I don't make it tonight, or am late, or if I disappear prematurely.
[Boolbar] Found it. Issue 44 (June 1985), pages 56 & 61, with ads for Atari, Dam Busters and Lode Runner in between! Actually says here you wrote it in 1982... took a while to get it published then!
[Darren] Sure did, by the time they published that I was into writing games written in machine code. The Atari is in the attic, I wonder if it still works . . .
