Ride your boat through the waves pulling wicked stunts. When you are on the water, pushing right accelerates and left decelerates. Press a button or space to jump or just get air of some huge wave. When airborne you cannot speed up or slow down, but you can flip your boat over by pushing up or down. You need to land with your hull aligned to the surface of the water or hull damage will result. When your hull is gone your boat is toast. Remember to not be a bad sport and jump over the heads of the people in the life preservers. They leave a nasty dent on the hull when you hit them anyway, so try to avoid. Visit the Play now! URL to give Tidal Upsurge a try
