An Abe Odyssey clone eh? I don't know what I'm taking about though.

They all used to be the yellow background, but I edited the one as my Steam profile pic to try and match the background to my profile background. For whatever reason I just decided not to change the other ones

That's an interesting mechanic, I'd love to see more games with it.

Do you have a different background color for your avatar on some media platforms? Pink for steam, yellow for YouTube, any others?
