I remember that puzzle. It involved turning around disks until they all lined up. Fun, but very frustrating at higher difficulty levels, and pretty boring after you did it a couple of times.
Perhaps we need to collect all versions on a single place? And also all other games... Not trying to suggest anything, not at all .

Just letting you know, the original 1.0 version had some nasty bugs if I recall. The final of that build was like 1.11 or something like that if I'm remembering it correctly.
