Thanks a lot! ๐ I'm glad you like it!
Haha, good catch! I just fixed the typo to "Background", thanks for pointing that out.
As for the file format, I usually use .rar since it's been around since 1993 and is the format I normally package my assets in. Thanks for taking the time to install a tool to open it—I really appreciate it!
I also uploaded a .zip version to make things easier for you.
Hope you enjoy the asset! If you find anything else that could be improved, just let me know. ๐
