Read the notes and credits and look at Scratch Cat go everywhere around the screen.
Although https://scratch.mit.edu/projects/104 is the oldest project to be shared on Scratch there is a way to still access https://scratch.mit.edu/projects/1 with TurboWarp or any other Scratch speed booster. I went into the game's code in TurboWarp and just grabbed the assets and inserted them in this project, as lazy as that. Now what's "ITTR" ? ITTR stands for "I tried to recreate" and then I try to recreate anything like this for example. It's also a new series I'm gonna keep making and it's gonna be pretty cool.
