Thanks for the feedback!
I'm not entirely surprised that navigation was the main issue with the game. It was a massive problem with the jam version which I'm still trying to solve.
If you have any more detailed suggestions for what would have made navigation easier, I'd love to hear them. I have a few of my own ideas (eg, minimap, better freelook visuals, progression gated enemies, etc.), but obviously I already know the map pretty well so I don't know how helpful they'd be.
