This puzzle is a lot like the floppy cube, but there are stickers on the inside layers and the puzzle has the ability to twist sides by 90° (half of a floppy cube turn) which can allow the corner pieces to be moved around and swapped around on what edge they are attached to.
The easiest way to solve this puzzle is to get all the corners in the right place then separate both corners from the edge and orient them.
