Thank you! :D The pixel art is all thanks to image-to-bitsy, and the "poem" happened spontaneously. And I'll be sure to tell the author of the soundtrack!
As for the problem, I tried both that and the version with embedding a YT video. Didn't work. Not entirely sure what happened - or didn't happen there, but I am working on a very slow laptop, so it might have messed it all up.
