Repulsion of the Alien Attack

You need to repel the attack of 50 flying saucers. At your disposal is a rocket launcher that shoots in three directions: left, up, and right.

Control of firing: keys "Y", "Ch", "C", respectively. You can shoot both individually and in bursts. This depends on the duration of the key press.

Control of the rocket launcher - cursor control keys. At the base, marked with the symbol "*", you can replenish your rocket supply. The number of rockets at any given time is displayed on the rocket launcher body.

It is forbidden: to shoot at your own base, to get under a saucer, and to let a saucer land on the base.
