Optical Illusion App

This Easter I was looking through my app store and saw this app for optical illusions, seeing as this directly links to my project as I am interested in optical illusions I downloaded it.
It seemed pretty cool very geometric, clean, simple.
As I progressed through the levels I became pretty into the game as it was very simple but I began to really like the presentation of each level each one became more intricate and unexpected than the one before it.
I would look at one level and it would be completely impossible but then i would rotate stand the perspective would change then paths would link up and the impossible became possible. It was incredible a optical illusion! I really like the creativity of each and every level the colours and layouts were also very fresh and new.
