Seems challenging yet fun
As I'm getting older, keeping my brain active by playing various games is important to me. This game was recommended. There are so many levels I will be very sharp by the time I finish!
Great brain game
Really test your maze capabilities. Very addictive! If you have a life don't download this game. Don't download this game if you have a full time job either. You have been warned.
My background sound cuts out when I open the app, otherwise an excellent gane
