Oops, Sorry about that. I'd better try and get that fixed... Somehow you're the first one who's ever run into that (or at least reported it to me).
Yeah, this is true to the spirit of these games in the past. There are also severe technical issues preventing the addition of such things. Minima and Anteform both use pretty much all the resources available to them in the PICO-8 environment. Generally I can't even change existing strings too much let alone add navigation. By design though they're actually pretty easy to map on graph paper as they're all deliberately very regular. Basically it's a matter of coloring in blocks versus leaving them blank, and floor sizes match.
With both games there's really only one dungeon or tower that's absolutely required, and when you finish that one you'll know it. The other ones can be pretty good ways to build up experience and gain gold, though.
