It may have been, but there's always more than one option.
I may not have described myself properly when I last spoke in here.
As thus, I have a picture.
The yellow indicates a rough estimate of where the boundries are. The red lines are solid platoforms, and as thus, cannot be fallen through. You can probably tell where I've added a bit of solid ground.
Green indicates fall-through platforms, so one may have more of a field to fight upon. I don't know how four people would fight on this map without there being some crowding going on.
The new spots I've added are the shrine being accessible and the roof above it being a fall-through, the solid platform a bit inside of the tower with the issue, or the one I was having an issue with anyway, with the roof above it, as well as the bridge, being a fall-through.
The final spot was that last roof between the two towers on the right. It adds another area of combat, which is useful to have in such a small-platformed stage.
I will admit the drawing was a tad rushed, but I hope you can understand it at least.
