The goop became a lot more expressive this update. You might get a smile if you actually succeed. You'll probably subsequently get a shocked, horrified face as you fall back down.
This has really just been a goop cosmetic update. New eyes, a mouth, and a range of emotions will make it harder to blame the goop for your mistakes. I also fixed an issue with the goop shrinking a bit while in the air and made it look a bit more... blobby? A fine looking goop, to be sure. I dare you to find a more handsome goop on Steam!
