Improvements to the game: When you leave Goldfish in their pools to become Whales they should not disappear once you log off. Also a "Fish Storage Area" would be good so you can save the ones you need as raw materials. Losing everything every time you log off stinks.
I've got a bug on level 39, it says "level failed" after the first gas station blows up and before the gas truck can make its way to blow up the other one. A couple of times it says "level failed" at the same time the second gas station is blowing up.
