This is a reupload of the oldest project on Scratch, with the ID of 1. I don't know who made the original, or if there was anything in the instructions or the notes and credits. All I know is that the original was the first project on Scratch, and it's unshared now. TurboWarp lets you play unshared projects, which is how I found this. Check out the original here: https://turbowarp.org/1 You can even verify it's the same code, thanks to TurboWarp's editor feature! UPDATE: TurboWarp no longer lets you play unshared projects. You'll just have to take my word on this (and also the comments). The cat should've been saying "Hello World!". I'm disappointed. /joke
