Coherent artwork, suitable sound design (albeit the flying jellies are a little loud), and oh so satisfying human-flinging action! I especially enjoyed the player bubble's facial expressions, and the screams. Oh, the screams...
Although is was a little tedious to have to watch the landing animation every time I died, and the intro text for some levels was too verbose to read at that speed, I nevertheless managed to make it to the end, bagging 900-some-odd hoomans along the way! Superb vacation location for jelly! :D
