I was playing through my old games today and after cringing through a lot of them, I came across this buried and forgotten dusty diamond... dusty, because of the HORRID facesets player complained about since the very beginning.
So today, I took them out.
And now the game definitely feels like a more upgraded version of Onyx 1, which it was intended to be.
It has come to my attention that there was a slight error at the later stages of the game, specifically at the Lezeer Building. So, just use this download, and carry over your save files to the "new" game. :)
