I like the tutorial that introduces a new type of block to us each level. Game was fun to play, though I did have an issue with the ball occasionally being hit in such a way that I had to wait an extended period of time for it to bounce down in a very small zig zag pattern and once it hit the wall at a 90 degree angle and just continued to bounce back and forth indefinitely. A return ball button would have been nice, or even just a restart level option.
