The music is great. Loved the sprite and the acceleration based controls. It was not clear for me why I was losing tho, so maybe a tutorial (even in the game's description) would be good.
Make sure you configure the Stretch settings on Godot, so it handles the window's resizing for you!
Usually it's better if you can make it enbended, so people can play it directly on the browser tho, it's easier to get more feedback that way.
And when exporting a Godot game, you don't need the entire folder, only the exported executable, it'll lower the download size and make it cleaner.
Great job on your first Game Jam!
