12+ Hours into LD22

I knew this was going to be hard but I didn't take into account how easily I get bored of things. Staying focused is becoming a struggle. Still not much to show but I fixed tons of bugs and enhanced the dialog system.

Still left to do (before tomorrow):

• Fix algorithm to calculate position of popup dialog bubbles (3D to 2D conversion)
• Weird spiky FPS issue (keeps jumping between 150 and 180)
• Collision detection on 'Level Advance Holes'
• Holes are currently black boxes instead of being cut out of the ground
• Still need to render a wall at the back of the cave
• Mobs and items can generate on top of one another
• Shadow casting
