Sorry to bring bad news, but the Putty game was released as 'Super Putty', and I bought (and still have) the CD32 version, at the same shop where I bought the CD32 versions of Trolls, James Pond III, Brian the Lion, etc. There was even a cover floppy of what I believe to be an ECS version, on a magazine in the states. Thats probably in a box here somewhere.
I still occasionally have a vivid dream that I discover that Amiga shop in a new location
off the main drag, full of parts, games, systems, and racks of magazines, like in days of yore...Trolls and Super Putty are my favorite Amiga games.
