Shockwave weapons

I didn’t do what I planned on doing, but I did do a shockwave weapon.  When I first saw the shockwave in action, it suddenly felt a lot more like a game.
The keys, updated:
1 for normal projectile (I’ve turned bounce on for both it and the
shockwave weapon)
2 for the laser
3 for the shockwave
q to quit.
= and – no longer change mouse sensitivity, they now control how fast enemies spawn.  Crank it up really high and wait for a while, then use the laser, it does an amusing digging effect.  Or drop it low and use the normal projectile and fill the screen with bouncing bullets, see how many you can get on screen before the game slows down.  The number is surprisingly high.
