On the Subject of Simon Stumbles

Have every flash be a “slot” with three properties: Remembered Colour, Flashing Colour, and Spoken Direction.

When told to remember a colour, set the flash’s Remembered Colour to it. When told to forget the current remembered colour, empty out the flash’s Remembered Colour. Pressing and stumbling refer to actions done on the module.

Note down the initial order of colours on the module, then stumble.
Then, every stage, for every flash:

• If the current order of colours matches the noted initial order of colours, press the Flashing Colour, remember it, then move on to the next flash
  (unless this is the last flash of the stage, in which case stumble).
• If the current flash has a Remembered Colour, press it.
  • If you just pressed the flash’s Flashing Colour or the Spoken Direction, forget the flash’s remembered colour and stumble.
  Move on to the next flash.
• If the current flash does not have a Remembered Colour, use the table below to obtain a direction. Press the obtained direction.
  • If you just pressed the flash’s Flashing Colour or the Spoken Direction, stumble.
  • Otherwise, remember the pressed colour.

		Flashing Position
		Up	Left	Right	Down
Flashing Colour	Red	Down	Up	Right	Left
	Yellow	Right	Left	Up	Down
	Green	Up	Down	Left	Right
	Blue	Left	Right	Down	Up

Upon a strike you will once again be shown the initial order of colours. Forget all flash’s remembered colours, then stumble to resume solving the module.
