It's my understanding from different comments I have read over the years, is what CU Amiga released is basically an unfinished port, it's still bug ridden and unoptimized for high end Amiga's.
It's unfinished, but I don't believe the Amiga version was just a port of the PC version.
Yes it has bugs, but so do some released games. There have been a couple of bug fix releases though.
http://hol.abime.net/1367 The sad truth is that anyone who could have optimised it to run well on the Amiga had gone onto greater things by the time the game was being developed and there wasn't enough money to justify finishing it let alone optimising it. If the source code turned up now, then that would change things entirely.
