I'm currently uploading an optified version of the port to Extras-Devel. In the mean time, you can get the binary packages here (install brainparty-data first, then brainparty). Don't worry about the size - it's all optified.

Binary packages:

• brainparty-data_0.5-1_all.deb
• brainparty_0.5-1_armel.deb

Source packages (use "dget"):

• brainparty-data_0.5-1.dsc
• brainparty_0.5-1.dsc

(If you are wondering: The package is split in two source packages, because I don't want to upload ~ 10 MB to the autobuilder every time I fix something in the code. You also don't want to download the whole game data every time the binary package is updated.)
