I really like the concept and the graphics are great.
I could see it being a 5 star if they took away the arrows that turn the cube and just let you move it more freely by tapping the screen. I play this on my iPad mini and the arrows are set way too low, so it's a pain to move the cube.
Also cut down on the annoying ads.
I almost start cringing when I finish a level because I know there's an ad right around the corner. E kinds of It's way too pushy.
It has the potential to be a really great game if they address these issues.
