I have no idea what the double r is about, but I do know that Sworrd Buster is rreally good fun.

Using the WASD keys to fly around, your character grabs the 'sacred magic sword' before being persistantly attacked by the guardians of the sword until death. Holding down the mouse button unleashes the power from the sword, but you'll need to recharge every few seconds.

I really like this game for a number of reasons. The movement feels great and blasting the sword's beam at enemies so powerful. The way the beams seem to bend in a spiral is also pretty cool.

A nice little timewaster. Grab it from the Overbored blog. (direct download link)
