In Heart, you will embark on a heart-to-heart journey through blocks. A translucent cube, inside which a heart beats, wants to make the world better, kinder and more cordial, and he has such an opportunity. It is enough for him to touch the block and it turns into a pleasant green color and becomes completely different. But you cannot step on the same block twice, this is overkill. Therefore, at the beginning of the path, make a plan for the movement of the heart in your mind so that it goes along all the paths and returns to the place from which it began to move in the Heart. Use special portals if there is a void between the sites. The portal can be entered several times.
