Footsteps of horses and animals should be highlighted in some way. Right now if you want to efficiently track an animal you have to either disable the grass and make the game look bad or modify the png file to change the color of the footsteps (but you lose all transparency in doing so, making the steps appear as ugly white squares ingame).
At night, it's almost impossible to see the tracks on the ground.
Maybe change the color to something more visible, or highlight the steps with a faint light so we can actually see where we're going.
Just my opinion as a new hunter.
