This is a rather wll thought out game. It's easy to learn, hard to master. The mechanics are straightforward and the 'rules' are easy to remember. My record so far is 6 rounds won, and I am sure there are those that can do worlds better.
As it stands this game is a wonderful time sink. I feel it might be better if the timer could be toggled on, or off. And, if you are able t in an update, or revamp, add the option to give the game different color themes, or more difficulty with more squares to choose from. But, on it's own, it is a fun and simple game.
