- Musical Gameplay: Starting from an ambient track, the music builds as you progress through a level.
- Songs in the Key of Panic: Played straight in the timed mode where the music speeds up as the time runs out. Inverted in the puzzle mode where the music slows down as the player is nearly out of pushes.
- Variable Mix: See Musical Gameplay above.
You ran out of pushes. Campaign failed. Congratulations! You've reached Campaign level 29. What would you do if you couldn't fail?
