One of the things I love about the Commodore 64, is where developers try and convert titles from 16-bit+ platforms onto the machine, and this is another attempt at doing just that, with conversion of the classic Amiga title.
This focuses on the tunnel section in particular, which is very impressive overall. It doesn’t work on a stock C64, and requires a REU to be able to run, but it is still seriously impressive to look at.
There isn’t actually much to do in the preview at all, apart from move your ship around and admire the movement of the background. So its a technical demo at best, and likely that it never got any further than this.
Who knows, maybe with the resurgence of new C64 games of late, this could get picked up again and finished – but it seems unlikely now.
