Here's what the orchestration looks like.

Maybe Villainess Level 99

If f(n)=n-1 > 0 → n-1 Loser!

I dismissed the idea that the folder name prefix would have been the issue because I had tested the game by exporting it to windows, and everything worked fine.
(4/4)

The app would run if references to those meshes were removed, resources were set to Local to Scene or if the meshes were made unique. On a whim, I decided to rename the mesh containing folder from "_models" to "models". Apparently the prefix "_" flagged Godot to not export that folder.
(3/4)

I then installed the apk to android through Godot and was able to use logcat to see the errors. It was mostly missing meshes not being properly loaded. I was using .res and .tres meshes, so I generated some scripts to batch import as .mesh files instead. Unfortunately the errors persisted.

Haven't played this one yet.

This is what the orchestration looks like so far.
