Can you specify what happened at the end of level 2? It's the level I spent the most time and care on so that's heartbreaking to hear.
As for getting lost, it is (sort of) intentional; I wanted the world to feel distorted warping and dark, specifically in the first 2 levels as a way to contrast with the 3rd level. Visibility was something I struggled to balance a lot during development (And while making parts of the levels because for some reason Godot doesn't give you an option to disable the WorldEnvironment Node in the editor), and while I don't think it's perfect, I think I managed to reach a somewhat happy balance.
Glad to know you enjoyed!
