For something simplistic, this was really good. I didn't understand how to advance. I thought the other squares were new levels. The levels just went on forever. I'm glad I figured it out. Some blocks were pretty annoying.
It was hard at times for it to be rewarding. Wait, does that mean? The music was good not that I really listen to it. I even love the title. There were a lot of things to click that left you outside the game.
