Thanks for telling me about the jellyfish. Those sneaky game-designers.. they could at least have bothered to add some small white bobbles going into the fishes mouths or something else that showed them sucking the air in better.
In other news, I've played through all the Greece levels now, and have nothing weird to report
Egypt seems like a tough place though.. How do one get past the traps with the falling flames? No matter how I try I can't seem to get past them without losing some health. Is this another jellyfish-concept maybe?
