Thanks for the feedback!
Regarding the seemingly unexplained death: While I don't know the exact details, I suspect this may be due to a lag spike that occurs when first entering that area. We couldn't quite figure out the reason why during development or find a fix, though now suspect that it may be related to https://github.com/godotengine/godot/issues/87843 or https://github.com/godotengine/godot/issues/103308.
