Diamond Rush Perfect Walkthrough: Angkor Wat Stage 8

You need the Freeze Hammer from Tibet or Siberia Stage 6 to unlock Angkor Wat Secret Stage 4 from this stage. But you don't need it to get any diamonds, you can get all 4 perfect messages without the Freeze Hammer.
About this walkthrough: I call it "perfect" because it shows you how to get the 4 possible perfect messages (all purple and red diamonds, no hits or retries) on every stage in the game.
