A couple of things - yes, the map generation is painful (ears and mental state). I think a pre-gen .z80 snapshot might at least get people playing.
The key choices seem odd: [qaop] to move the cursor says the screen ... okay(!)... but it appears to be QAOP that is moving cursor, leading to ever downward movement when the Swordsman is selected being interpreted as 'A' (attack) and then down.
Then there's the mildly annoying d (from 'end' in the UI) that doesn't get deleted when you select a character.
I really wanted to love this, as I think it's a super brave attempt (you've got unit A.I. and a nice map in place), but the player is left a bit in the dark, thanks to it lacking the 'gloss' (or just comprehensive instructions) that'd make it a gem.
