please make a Amiga Port
An Amiga version would be extremely cool but unfortunately the engine I'm using, GZDoom, isn't available on the Amiga. So it can't happen unless someone ports it, and I'm nowhere near a talented enough programmer to do this myself, if it is even possible. There is an old version of the original ZDoom from 1999 for the Amiga but it is missing A LOT of features and wouldn't be able to reproduce AB3D to a satisfactory degree. Sorry!
Currently you need a mostly up-to-date GZDoom to run it. It uses some features that are fairly recent. Theoretically there could be a version of Osiris that works on an older version of the engine, but depending on how far back you want to go, it could be a lot of work and could have features cut out. I don't really have any interest in doing that myself I'm afraid!
