Since I've never played the Amiga-version, I can't really comment on that
other than I've tested it under emulation for other consoles/platforms.
But I did own it for the C=64 even further back, and it was utterly playable.
Even a kind of revolution, original in the genre...
P.S; I vaguely recall the ability to "lock and strafe" under C=64...
Hmm, maybe I'd need to take another look at it, with a logitech dual-stick control :p
