Blockage is a fun full-screen breakout game, where the bricks explode when they are hit. The graphics are decent, but there are no sound effects or music in the background. There are many types of bricks that behave differently when hit. Some just explode, some take several hits to destroy, and some re-appear after a while. Overall, it's a very entertaining game and worth the less-that-one-second download (even on dial-up!).
