Alien Swirl - Program Power

Alien Swirl is a fast paced space invaders clone for the BBC Micro with frenetic levels that are action packed but ultimately, a bit repetitive. There are only a handful of aliens on screen at any given time and its difficulty is a function of both the games speed and an increasing number of aliens as you progress through the levels. Given the game's speed, the rendering of aliens, missiles/bullets and so on is quite flickery.
