The patterns of the colorless guards are random. They either choose to wait 1, 2, 3, or 4 seconds to turn around, so you need to strategize and think fast or they will catch you.
The guards were inspired by EarthBound's hieroglyph enemies that you find in Scaraba's pyramid. Also, Blue's diagonal sprites were inspired by EarthBound. If you want to remix this, then please change something in it. Thanks for playing! -Derpy-Cheese
