Thanks for suggesting it and for the test run – I don't see why not (though from a technical standpoint the run is fairly similar to the current Any% – just slower). I wonder if with this run it may make sense to keep a magic-user who can cast Haste, which doubles the moving speed when inside dungeons.
Other potential categories could be 100% (whether including all minor caves and all items/spells or just all progression scenes), Damageless% (this would be quite toxic but definitely feasible), the meme category Fist% (no weapons or spells allowed, just bare hands)... and someone mentioned Cat%? ; )
Awesome job investigating — thank you and Ouija for this. As a note for viewers: having access only to M1 Mac, Genesis Plus is the only emulator working for me as of April 2022.
