Hello. First of all, i want to say, that game is very nice. I like the idea of combining main rule of 2048 with elements of tetris. But there is one thing, which can be changed. I'm talking about "mystery box". I wouldn't want it to be removed completely. Just to add an option to choose to play with or without it. I understand that "mystery box" is here to add more challenge and difficulty , but I'm sure that some of people who play this game would like to try it without it.
