Graphics matter a lot in this game. The visuals are simple but i think they work well. You use your mouse to aim and shoot at the ufos. Destroying a ufo increases your score and you survive waves of aliens. The mechanics are straightforward for all players.
Clicking is how you start the game. You must use your mouse to aim and shoot at the attacking ufos. Survive the waves, destroy the aliens, and get a high score.

I think it is better then just clicking randomly. You should try to destroy every ufo to get a higher score. The features are the alien attacks and the simple shooting. My personal discovery is that you survive longer if you improve your skills.
