Please create an UNDO button – 1010! Block Puzzle Game Review

It's a smart and enjoyable game but there needs to be an UNDO feature. Just for better strategic play. My suggestion is that for every time it gives you three new pieces, the player can undo the first two moves. Once the third piece is placed, that's it. You can't undo it and three new pieces are given. Thanks.
