Update: The shark now moves decently faster and eating scientists now gives you slightly more health. I hope that this as well as the tip section below help to make the game a little easier. Good luck and have Fun!
You play as Boot Stick Shark, a shark vigilante on a mission to save his friends. The evil scientists captured Boot Stick and his friends and Boot Stick was the only one able to escape.
This game may seem hard at first, but once you get the hang of it its not so bad. Make sure to keep going after the first stage because you get a new weapon after every stage.
1) Save the ice beam for when 2 scientists are standing back to back, you can freeze them both and noone will attack you from the other side while you attend to them.
2) Some people have claimed it is easier to constantly head in one direction despite the scientists coming from the other side (except it is probably best to turn around to kill the robots).
3) The rockets are only effective against the robots.
