Thanks for that. I appreciate your checking it out and sharing your valuable insights. I've worked in Unreal since the early 2000s, and evaluating Godot was the entire point of my doing this jam at all, so your feedback is greatly appreciated. One serious problem is Godot's webgl performance tanking with a sub viewport, even one that has zero draws. And I'm not thrilled with tilemap nav performance either.
But, I've already made a build with some changes to how I'm doing the minimap, cat-sense blips on the edge of the screen, and navigation recalc. I'm going to ping you after the jam to see if I nailed them.
