Game Maker Spiral

http://www.mattmakesgames.com/ -- Fight off the Woes for as long as you can and go for the top score! In this uniquely minimalist and supremely balanced Arcade/RPG hybrid, you shoot at the Woes from your fixed point in the center of the screen, trying to deflect them before they reach your heart. Gain level-ups as you fight to increase your strength, and kill as many Woes as you can without being hit to score huge combo bonuses. Unlock new game modes, special attacks, and more as you play, then go to the stats menu for meticulously recorded statistics on every aspect of the game.
