Most of my problems with this game is the unnecessary big map it would be better if the map were smaller
I have done some map making with RPG maker myself so this just gonna be a suggestion
Most of the build should be able to see at least 80% if you're in the center
If there were a big map just make it like 4 time bigger than the normal one
Dont leave a place just for walking, have some in-lore reason or some NPC for flavor text or something similar
If you really have to make a big map have some sign for what purpose those places serve
Love your game hope this will help
