A great, enjoyable puzzle game! Once you have worked all the puzzles you will be wanting more b Similar to physical block puzzle games where you have to build a shape from the pieces -- Except in this game you also have to what pieces the pieces are and how to make by overlapping the pieces given. The game has a very minimalist aesthetic that serves it well and nice a "zen" soundtrack. Some puzzles range from easy to frustrating, and an individual approach can make the same puzzle both. If you look closely you will notice there is a grid to help align and cut pieces into new shapes. Also all puzzles can be solved without needing a piece to extend off the puzzle area. Great fun! You should buy this app.
