This game is really fun, but I wish I could figure out how to get into the hidden sea level... =/

Easily the best flash game I've ever played. The levels are challenging, but not frustrating (with a few exceptions.... there are a few later levels where I can't figure out if I'm doing something
wrong or if it's the game's fault). Regardless of my difficulties, I think this is the most re-playable game on the internet.
