This is a variation on the standard breakout game, but this version is quite original. There have been many take-offs on the classic, and I enjoy some of them, but this is the first that really strikes me as unique.
Some reviewers of past versions have mentioned that there weren't enough levels. On this version, anyway, I see that there are 50 levels. Considering that I noticed a big jump in difficulty starting at level 10, I would think that 50 levels will be adequate for a while.
Admittedly, I just started this game, and it's possible that my opinion could change down the line, but at this point, I find it to be a very enjoyable and compelling game. The design, layout, controls, and even the music, are all very well done. If you like brick breaker/break-out/Arkanoid games, give this one a shot.
