But... it's an update.
-added "trembling" to squashers
-character flies up a bit when squashers touch down (he only goes up 1 pixel right now, I didn't know if more than that would be overwhelming the effect, see what you think)
-the gun shoots
As for now, I think I'll optimize it a lot before I add the enemies, so there might not be updates for a while.
EDIT: forgot screenie
EDIT2: wrong screenie- now it should be okay
