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. Take a look: Get it here: https://play.google.com/store/apps/details?id=com.fessios.blockbuilder
What's the chance you were the one who made the game? If you're gonna spam your adverts, at least admit to it. That said, your game looks pretty awesome.
To be fair, they did say "I have found a way to refresh this classic", clearly implying ownership. Don't be too harsh, this is on-topic for this forum and if nobody cared the thread would get buried anyway.
