[GAME][4.1+]Eye test - Spot the Odd!

I have been working on this Eye Test Game for a few weeks and now it has reached a stage where it can be released.

I used this project to learn about Material Design and I incorporated some of the new components in the app such as Navigation Drawer, RecyclerView and SnackBar. It was fun but now it’s time to take the big leap and see if people like the concept.

The game is fairly straightforward: you need to find the odd colored square in a given time.
