Mario 63 (the 2D flash game based on Mario for Nintendo 64, has many of the same levels) has the Tick Tock Clock. When you access the level, you see a background with other platforms, and even a yellow star and blue angry smasher in the background (third section only I think). This is expected, many levels show other parts of the level depending on where you are. (snow level shows the opposite side in a 4 sided view)
What is unexpected is that there seems to be no way to access all of that activity? Is it true that they designed in all those moving parts and platforms for background only? Or is there a way to access this background section?
(the outside of the clock has no arms, just the numbers 12, 9, 3 & 6.. so I guess it doesn't have to do with the timing when you enter.. dunno)
