Brickdoh v0.59 got a more precise timer, which should help to smooth movement, and a small fix for paddle-ball spin handling. Also there is one more level, and a new brick type waiting for you.
To run Brickdoh, just download the brickdoh-0_59.jar. If you have Java 6 or newer properly installed, a double click on the jar file should start Brickdoh. If this doesn't work, please check the project Wiki for instructions how to start:
The brickdoh-trunk.tar.gz archive contains the sources, images and sounds for this release.
