Awesome puzzle game
Both idea and visual are nice and simple.
I like playing Minesweeper. And I really enjoy this game.
It's not really like Minesweeper but it is similar in some ways.
It does require your thinking but, for me, I could say it's a relaxing game. It does not put you in a trance, not that kind of relaxing moment. But you rather give all your focus on the game, careful not to make mistakes. And when you give your total focus on something, you don't think of anything else but the task at hand. That, in itself, is kinda relaxing, providing that the task is not too stressful. (For me at least). Therefore, I enjoy every moment of it.
Again, this game obviously isn't for everyone. Some people don't like thinking that much or don't like this kind of game in general. I guess you can ask yourself whether you like Minesweeper or not. As I said, they share some similarities. Still depends though!
I don't usually give stars to these kind of games. 0.o
