* General proofreading for grammar and spelling
* General formatting
* Addition of appropriate literals where appropriate, i.e. `&"foo"` for `StringName` cases and `^"foo/bar"` for `NodePath` cases
This leads to code that is easier to understand and runs
faster thanks to GDScript's typed instructions.
The untyped declaration warning is now enabled on all projects
where type hints were added. All projects currently run without
any untyped declration warnings.
Dodge the Creeps and Squash the Creeps demos intentionally don't
use type hints to match the documentation, where type hints haven't
been adopted yet (given its beginner focus).
Also converted the PNG files to lossless WebP and removed an unused .import file while I was at it.
The rest of the changes were done automatically by the editor when I opened the files.
- Increase gravity, player speed and air acceleration for a less floaty
feeling.
- Clean up the code to use constants when relevant and remove unused enums.
