This is a little game I made for school children in order to learn while playing.

You have to collect the right battery number by performing the proposed calculation.

When all the battery is full you complete the game.

If you make a mistake, the batteries will become monsters.

There are also monsters that will try to kill you. 

You can use your laser to destroy them.

To play user ARROWs or WASD + Space to Shoot
