Add Ron Mak mode

Some crazy difficulty.

Ideas

• The game becomes bullet hell
• Screen or player rotations
• Changing patterns
• Boss battle???
  • May need to incorporate either projectiles (player's gun) or "helpful blocks" that do boss damage when you run into them. The latter is much easier to implement with the current code.
• Seizure-inducing rapid color changes
