Wow! Nice job! And thanks for sticking with it that long! If I give the game any more dev time, I'll probably break it out into levels that introduce the mechanics--and definitely tone down the whirlpool chains.
Actually, if you angle your entry just to the left of the whirlpool center while rowing in a bee-line fashion, the way the whirlpools work makes it fairly easy to use as a speedboost.
