Hi there jgmarsar! Thank you :)
That means you're still on the old 1.0 version of Ynglet. If you're downloading directly from Itch.io, then you have to go to the main page and download Ynglet again. If you're using the Itch.io app, then go to your library and find Ynglet under installed games. Now right click on it, and select check for updates. This should start downloading the latest version.
