I bought this long time ago.
Reviews seems to be still great, but i have to say this was a huge mistake. Im not sure if issues can be fixwd after years, so i want to ask you.

Is there any patch, port, anything to make this game playable for humans?

Reality is quite sad, maybe its funny classic RPG, BUT this game is pure nightmare if we´re talking about controls and its sensitivity. Stuff for nerds which are happy with extremely clunky mouse controls and game speed which looks like10 FPS at best?

I remember many 90s RPs with slow controls, but this is extreme patience trainer, not a game.

what, specifically, would you change? what could be better with the controls?

i created an UltimaHacks project which is a patch that changes the controls a little, but perhaps not in the ways you're looking for:

do you have any specific ideas for how to make it better / faster / whatever?

Not sure what you're looking for, but there's also Exult; http://exult.sourceforge.net/download.php
