Square blocks arbitrarily occupied the playing field, and you had your own plans for this space. Now you have to deal with the invaders first and for this you will have a special tool - square shapes. If you install them on the selected groups of elements, so that the form completely coincides with them, you will achieve the removal of unwanted objects. Yellow tiles can be removed in one move, and on objects of other colors you will need to install the template twice, or even three times. Make sure you have enough pieces to fight the blocks in PULZE.
