Ben 10 Saving Sparksville

In this game Ben 10 is fighting a giant robot created by Megawatt. The robot is walking towards the hydro electric dam to power up. You must destroy it before it succeeds. Ben 10 has converted into Heatblast for this purpose. Heatblast is flying on some sort of board and shooting fireballs to the robot. The robot picks up cars and throws them towards Ben 10. Your goal is to avoid these cars and to hit the robot with fire balls.
