Thanks for giving it a shot, I'm sorry about you getting stuck in the geometry. Though as far as I know it's a freak bug with Godot, that occurs very rarely. Will try to remedy if I can.
Regarding the talk about the double genre, I understand where you're coming from. However, I feel confidant that if I combine them well enough it will become better than the sum of its parts, or at least be a unique experience. In the unfortunate event that I can't make the dungeon gameplay worthwhile, I'll do what's necessary.
