I’ll try to get that area if I can, though I find the area isn’t always exact. Sometimes some areas work and sometimes they don’t.
The eagle I get roughly the same clickable areas you do in Full Screen mode. In “Borderless Window” mode, it’s almost unclickable- it only works right at the bottom, and sometimes not even that works.
As for the wings and the axe- it could be a loading thing because after they’ve loaded for the first time, all areas are clickable. Dead-centre with the wings is an issue on the first click, and the right-hand side and centre of the axe are issues on the first click.
