This would be a great way to solve the terrain issue but I think having to redo so much of the art would be too time intensive/high production. How about instead the devs implement a simple color coding tile system which can be toggled like the “ALT” and “CTRL” keys. A player could press “INSERT” and the impassable tiles would turn black. So in regular view you could tell whether said tile is a tree or bush or stump and the “INSERT” view could tell you exactly where you could walk.
