Ok I just did a quick and dirty port to OCS/ECS 64 color EHB mode.
The first BETA (v1.01) is in the Zone
You'll need a fast 030 card to play this and it will still probably be very slow.

Obviously it won't run anything like this fast on an 030 OCS/ECS machine but it's the only one I've got for testing
Looks pretty good for only 64 colors though I think.
Each frame this version has to convert each pixel from 256 colors to 64 colors and then convert it from chunky to planar.....ouch!
