Mountain King has a hidden level (called Glitch Heaven) which can be reached by jumping from the tip of a ledge located on the mountain peak at the top of the game screen. Timed correctly, the player will catch the very bottom rung of a higher ladder. The ladder leads into a hidden level of ladders and platforms. At the very top of this area are two strange ghost-like figures, but there is no reward or bonus for entering this level, and the level is extremely difficult to navigate (with falling from the various ladders a common occurrence).
