As a huge Tetris fan I am always looking for new challenges. With BlockBuilder I have found a way to refresh this classic! Block Builder has no walls and the blocks do not fall from above, but from all sides. However the biggest difference is that the goal are not complete rows but gapless squares with the side length of at least 4 stones.
I like this game! The graphics and the animation is well done. I could understand the game very quickly. Besides the pie chart. The icons for the powers are also not intuitive. Without your guide I would not know what they do.
I think you could improve the icon of your game in Google Play. Because it does not match the desing of the game.
