Fun project! I love the small visual detail of the air drag that appears behind the player.
An important note, your game struggles to handle different screen resolutions. I recommend going to Godot then doing the following:
1. Go to project -> project settings -> display -> window
2. Scroll down to the "Stretch" settings
3. Change the Mode from "disabled" to "viewport"
4. Re-export to itchio, now the game should work on all screen resolutions!
Fun little game though! I hope to see more games from you in the future!
