Awesome is a remake of one of my first ever games. The aim is to shoot the enemy at the center without being shot. You move around the enemy and it unleashes a variety of attacks:
-blobish shaped bullets, that it fires whenever you shoot
-lines of triangles that move really fast
-cog shaped discs that explode to create more of themselves
-big high damaging spike that rotates towards you
The game is over when you die, there is no way to win =P
