French developer MXP4 says they want you to “play with your music.” They just launched Bopler Games, a set of classic games on Facebook with an added musical slant. To play, choose a song from the Bopler library, (which features an inordinate amount of 80s pop) choose a game, and go. The kicker is that each of the games automatically syncs to the beat of your chosen song, creating a potentially exponential growing set of variation. Shmup enemies dance to the beat, Tetris blocks drop at different speeds depending on the speed of the song, etc. At the moment, there are four games available, including versions Tetris and Snake, with six more on the way.
