possible to make diablo in amos ?

Does it matter though?

Surely this method if written right would just use paste bob for the "floor"/background as an alternative to using paste icon (which iirc lacks transparency)

You would optimise to only use a real bob where you need to go behind an object, thus reducing the overall bob number considerably

The floor sections are diamond shaped and interlocking so that they always overlap.

Then get smart with graphic design and draw tiles that are the overlaps required

Something like Cannon Fodder which is faux-isometric

I'd sooner narrow the visible screen by putting status bars on the left and right border using sprites as if they were screens.
