released a free Back to the Future game on Facebook called Blitz Through Time. It's a pretty straightforward Bejeweled Blitz ripoff, though of course it's skinned up with sounds and graphics from the classic movie series. Your goal is to match three or more same-colored gems in a row, pushing the in-game speedometer all the way up to 88 miles per hour, where you'll ... change the background to a different time and start matching gems again.
Fun? Sure. New? Not really. But if you're a real BTTF fan, "liking" the game on the fan page will enter you in a contest for some related prizes. You can see a short trailer for the game after the break. Of course this is all promotion for the actual BTTF adventure game, which comes out sometime next month.
