I really think that this is a future implementation but, if not, please, consider make environment sounds for the game. What i’m saying is sounds of insects on the florest (like crickets, frogs or whatever make sense at the map), fresh breeze passing through the tree’s leafs, waves sounds if had a beach in the map and so on. Even that the BGM have a really good quality, has time that you just like to turn off the musics and listen the world, the things get more vivid.
TL;DR: The game needs environment sounds to look more vivid and comfortable to play.
