This puzzle is new and interesting, however, even with a tutorial, a clear idea, many retries and the meaning of the image i am trying to decypher its still an unfair game, and too big for what it is. I would have liked like 3 pages for each difficulty, but.... there are eleven just for the easy mode, and you thought that this would take 30 minutes for people to complete each one (i could do some of them in under a minute) so its kinda if like you dont know what its going on with this game.
Also, a shop? why? there is no need for it, its a puzzle game, not upgrade complete 2.5
