Impulse

Embedded in a sea of enemy particles, players must avoid collisions as they
propel their own particle to the goal. New levels bring new challenges and
new forces to contend with. Players have to budget their energy use as they
grapple with gravity, electric forces, and the effects of Newtons laws of
motion.
Hint: Be Patient, dont get click happy. Click on one side of the green
particle to create an explosion which propels it in the opposite direction
towards the goal. Closer you click the faster it goes.
