Level Variables

  • 0405 - Queue for EXTEND letters (Only 3 will come per level, any queue excess will be cleared at the beginning of the next level with openings)
  • 040D - Timer countdown until "Hurry!" appears. This set to 040E at the beginning of each level.

  • 044D - Remaining levels to be skipped by an umbrella. If > 0 when all the enemies on the level are defeated, you will being skipping levels. You can only skip 31 levels max. If the variable is set above $1F(31), skipping will occur again after the defeat of the enemies. This will continue until the variable = 0.
  • 045E - Timer going up (Item appearances/disappearances may be relative to it)

- 0449 is hundreds
- 044A is tens

$27 seems to represent a blank space. These reset to $27 (36) at the beginning of each level. Could possibly be related to how the on-screen score information is redrawn.
