Just found this page while searching for “The Great Giana Sisters”. It brought me back several years! Armalyte was an amazing game, but it wasn’t the only game by Cyberdyne Systems on the C64 AFAIR. I could almost swear I played a platformer that was released on a Zzap64! cover, did they?
Woo! Pics, demo downloads and information about Armalyte 2 and a link to download a “competition” version with built in trainer.. I would have loved to have seen this 10 years ago..
