Turbo mode! (shift + green flag) Press space or click to show variables/lists. If you would like to remix, just change the I love cats backdrop. Propose to be feature here: https://scratch.mit.edu/studios/4228481/comments/
I finally made one of these! I have wanted to for a while, but only did it now. I tried to speed up the process of scanning the image, so I hope it works when you remix!
