I see a few mistakes in the top part of the puzzle.

Basically the upper right purple square is missing the inside dark purple line.

The upper right green square is missing the medium green line along the top.

And the lower right green box is missing the medium green line along the top. And the dark green line along the inside left side.

Without those mistakes, the puzzle would at least be consistent.

This looks like a abandoned work with any amount of errors, 1 side is 3D, the other isn´t and the last not even touched. Could have been a nice one if done correctly, but this way I feel cheated...

Marvelous puzzle!

What errors? I found it logical and was hence able to finish it in 15 mins. There where no errors.

As a puzzle this is an excellent one.
It looks daunting when you first open it, but you can soon see the logic of the pattern.
The so-called "errors" are essential to the fun, otherwise it would be predictable.

Tiene varios errores, lo que le hace más difícil y pesado.
