-Funny intro animation / story (in my biased opinion)
-Tutorial built into the game
-25 levels, final boss, followed by a free-for-all level to compete for high scores
-Compete for highest ship destroy count, fastest time or largest asteroid mass
-Powerup selection after each level, many providing lasting benefits throughout the game
-4 different endings depending on your performance
-Many different enemy types and behaviours
-Play with mouse (my favorite) or keyboard
-Custom key bindings available
-Control your ally asteroids in a unique'ish way
Many comments and ideas from version 2 have made their way into this game.
Lots of work and love... I truly hope you enjoy it!
