Changelog 0.0.2.

I've had some friends test the game for me and they gave me some feedback and pointed out new bugs. Here's a list of everything I found:

Fixes:

• Checkpoints now correctly move with the underworld
  • This means no more spawning in lava!
• Player no longer bugs out and flies away after the world rotates.

Adjustments:

• Changed the overworld jump puzzle to be more challenging.
• Changed the shape of the platforms at the first puzzle in the underworld
• Made the hole in the volcano jump smaller
• Don't get discouraged, it really is possible!
