  * Shipwreck vault is solved reversed? -> Not reversed, just "half", you can normally solve orange. Seems to need pattern name.
  * Tutorial sounds don't always play -> Unsure. Not controlled by pattern name.
  * FEATURES:
+ * Start the game if it isn't running?
+ * Stop swapping colors in desert
+ * Look into valid panel swaps for keep walk-ons.
  * Randomize audio logs -- Hard, seem to be unloaded some times?
  * Swap sounds in jungle (along with panels) -- maybe impossible
  * Make orange 7 (all of oranges?) hard. Like big = hard. (See: HARD_MODE)
- * Start the game if it isn't running?
- * Stop swapping colors in desert
