Bugs

•  baddies pop out of the world
  •   Mitigated:  Each Room will bring back any enemies who stray.
    •   (Tough to truly "Fix" this as it seems like Unity's 2D Colliders simply fail to validate faces at certain rotations?  Might be able to lock rotations to 2 decimal points or something, possibly a float accuracy issue)
• snakes don't reflect off of doors.
  
  • Fixed: Double Collider fix for previous door bug had side effects.

Changes:

•  New Shader for Wavy Rooms
  • not more performant (or better really), just different.
