Star Rush 3 game

Very simple infinite scrollshooter in space. 5 types of alien ship: - Spy Drone (it has no weapon, so it don`t shoot at all); - Asteroid Marauder (single shots); - Planetar Marauder (triple shots); - Star Marauder. It drops two agressive drones after death; - Star Spy. It has four plasma dozzles and double yellow shots. And 2 types of objects: - space mines can kill you, but if you destroy it, its spikes can kill alien ships; - asteroids (absolutely harmless).
