v0.3 - Getting from there to here

It's been 4 months since my last patch and I apologize if the game seemed abandoned! I had to tear everything apart to completely redo the physics so that I could roll out a huge performance boost, since that was one of the primary complaints of the game. I've added lots of additional changes too while I'm at it! Changes: [list] [*] Quiver size is now 4 (was 6), and can only get 1 of each special arrow [*] The portal now opens and closes itself on a timer [*] Knights have a proper melee attack [*] Wizards have a proper spell attack [*] Cats are now obtained with cards (and you can get multiple) [*] Added cat upgrade cards [*] Decreased music volume [/list]
