Fixed menu, battle animations

Hello! It's Neils4. There is a little over two days left before judging for the Panic Horror game jam takes place. I am glad to announce that I was able to fix the menu system at the bottom of the screen so that it is no longer sticky. It works like a charm now! I also added some in-battle animations. The Demon Possessed Girl now levitates, the Zombie claws you with a moving hand, and the Poltergeist displays a skull on its screen when it attacks! I've been playtesting the game a lot and I found a bunch of little errors, which I fixed. The game is not perfect, but it's definitely a step up from before!
