This should make for an even speedier speed-run! The one on the site is great for playing as-is, but there's an even faster way to beat the game. Take a look at this video

What you do is hold the button to throw a ketchup jellybean, run back and forth to build momentum, then launch it as far left as you can. If you did it just right you'll see the final screen for a split second. Then throw another ketchup jellybean to get the blob back. You'll notice all the enemies are gone now! You don't have to slow down once and you can just breeze through all of Blobonia! I hear that you can do this trick with any jellybean, but I never tried that. I discovered it this way a long time ago.
I don't want this to be like a request or anything but I'd love to see someone zip through this as fast as possible using this glitch!
