IMPORTANT FIRST:
If you are an achievement hunter, never ever start it, as if you don't want to buy the DLC.
First start you get an initial achievement !!!
In my opinion, the amount of money you will spend on DLC is horrible, compared to what you get.

ADVICE:
You should use a large screen to play this game !!!

RESULT:
This game is okay, if you just want to solve some free puzzles.
