A few minor fixes, working on grenadiers, working on the music, ducking looks better now,  xbox controller support done for player 1
the visuals will be upgraded as superior art comes in.
The game is really hard right now, enemy spawn rate is really high.  I'll probably adjust it so the game can be played in a loop with the enemy spawn rate and aggression going up with each successive consecutive completion.
added shadows on many things, makes it look cooler
