Looking at the riddle,
You thought this would be topsy-turvy? Think again! It's a slide we are after. You can do it twice then.
This tells me that the rows will have to be turned twice.
The front, the sides, and the back we are after. The top and bottom rows, we'll spin them faster.
The top and the bottom row must be turned, as we are looking for the answer from the front, back, and sides
Colors will blur together, green and blue, Orange and red, let us not forget, will too.
If you twist the top and the bottom rows, green and blue will blur together, and so will orange and red!
Putting the cipher into cubes:

Applying the riddle,
Turning the top and bottom rows twice:

Using what @El-Guest said on your last riddlepuzzle:
the top left characters first, followed by the top middle characters, etc. gives us: supermariorpgittheonlyonejustformewheniplaythegameiwin
Adding spacing gives:
