While the art's nice, the game itself is mediocre.
I'm going to give this game my honest rating, and I won't go into a big speech about how overrated I think it is, but I just don't really understand how people are in awe by this game.
This game has some decent graphics, what with the scrolling city, the boats, the swimming people, so on. It has eye candy, like explosions and blur effects. But that's pretty close to all that's interesting about this game.
The gameplay is very, very simple. You move up and down, and you keep pressing A, and meanwhile, stuff explodes and dies. The only real variety is in the objects and people you pass. I like the little minigame-style feature of pulling down helicopters and planes, but was disappointed to discover there was nothing else like that anywhere in the game.
Overall this game feels 'choppy'. It doesn't lag for me or anything like that, but it feels thrown-together excluding the artsy backgrounds. The ActionScript, while impressive for things like chain reaction explosions and camera zooms, could have been much smoother for the controls and the motions of everything. The shark's tail is the only thing on the screen of the game that seemed to move with ease, which seems out of place when the rest of the shark suddenly moves in any direction without acceleration, seeing it suddenly shift in rotation going up or down.
Granted, this game did entertain me for a few minutes, mostly with pulling helicopters and planes out of the sky, but that wraps up as the whole game to me. Nothing really keeps it going, and only the explosions and the speed of the water give off the illusion that this game is 'intense'.
