Boing Boing recently ran a games inspired by music competition and a few of the entries were posted yesterday. Almost all will run in your browser, some are flash, some HTML5, and some unfortunately require other plugins to run.
I’m downloading Sean Monahan’s game, Beat Boost (entry page) at the moment but there’s also Knife Attack, Flatwar, Space Junk, Arctic Trek, Gobber Assault, Bounty Hunter and Infiltration.
