Aliens are without energy in their flying saucer and only you can help. Move the lasers in the right direction and get them back home.
It’s a logic game where you use pies to direct the energy for the alien ship. The number over the ship is important, it shows you if the beam of energy should be solid or n pieces. If you succeed you get a happy and satisfied green guy. Some levels seem to be very difficult and you will need many tries.
