First off l think the game is already brilliant. I think the only barrier to entry for a casual player (and a game needs casuals) is a hint or navigational system. Akin to a gps hint system - something like Ghosts of Tsushima (wind blows directionally where you should go)
I know that’s a big ask - technically - or suggestion, but I feel it’s one that would help tremendously with attracting more players. Active quest toggle and a hint navigational system.
