On page 4, there is a download link for the blue dragon. This works, but you end up downloading an svg file, not a png. Also, the download name is dragon-azul.svg. Renaming to dragon.svg, and using the same name in the asset_server.load line leads to an error:
ERROR bevy_asset::server: no `AssetLoader` found for the following extension: svg
I don’t see anyway to download the blue-dragon as a png from the publicdomainvectors.org website. Perhaps it might be worth hosting a png version with the code?
It is also very big - on my 4k screen, once converted to png it is off the sides once I expand the game window to the full screen.
