It's a really addictive game, you can clearly experience the reward of spending hours playing it. I loved how brutal everything would get if you hit a few devastating combos :P
The only flaw I see is the lack of a 'Return to Main Menu' button (or maybe I haven't discovered it yet)
As for the saving issues everyone seems to have, I'm running it on Chrome on Windows 7 and I've seen none so far.

All games should be like this one. I loved it. The extremely fast pace and all the havoc the shark would cause was amazing to watch, and trying to keep playing without cracking up was impossible.
