Every bullet has been redrawn BIGGER AND THEREFORE DEADLIER. Weapon Effects now produce slightly fewer bullets as a result, because we can't have the entire screen filled with doom.
Oh, also every weapon effect has a unique firing sound and there's now a sound when a bullet connects with an enemy. Workin' on the FUN effects. I've been hammering my face into LMMS (pretty nice for being entirely free, highly recommend it,) to try and smash together a title theme and map music, but I do not have a tremendous amount of skill when it comes to music.
But you knew that. You've heard the battle music.
Up next is either more music or sights and sounds for deaths. Player death, enemy death, the fun stuff. Still haven't re-done the flash bomb.
