Click the green flag, sit back, enjoy. Please check out the nice remixes made by other scratchers: https://scratch.mit.edu/studios/27457559/ And of course, feel free to remix yourself!
NOTE: It will lag a bit when you first start the project. This is normal, and it should work smoothly after. This remix adds a "trail', along with the ghost effect to make a pretty cool effect. It is also sped up a little. And by the way, I didn't count the code used to hide the thumbnail.
