Formatted code

[OverloadedOrama]

Run commands gdformat . and gdlint . from the godot-gdscript-toolkit to improve the code quality and ensure it follows GDScript's style guide and best practices. Functionality-wise, nothing should change. I'm working on doing the same to all of Pixelorama's codebase as well.

Note that gdlint still gives two Error: Max allowed line length (100) exceeded (max-line-length) error messages, but I'm not entirely sure what to do with these.
EDIT: Fixed in 13fd5cc

Also fixed issue with the main scene failing to load due to case-sensitivity.

Looks good to me, :) I will merge it but I don't know why files named "broken_1-8.png" are not in the PR if they are referenced in Main.gd. Could you add them or remove the reference? I don't know if it's intentional. :/

These existed before this PR, so I'm not sure why they are there either. This PR doesn't add any new lines to the code, it just reformatted already existing code. I went ahead and removed that code now though. :)
