The re-launch of the game didn't gather as many players as I would have hoped and sales has slowed down to a trickle in the last couple of weeks. The original game sold a lot of units on Xbox Live Indie Games back in 2010 and I fondly remember playing packed races online, talking to people over voice chat and strangers showing me shortcuts I didn't know about that they had discovered.
I would love it if the game had a small revival, but at this rate it's not going to happen. Making the game free-to-play is my last-ditch effort to get new players into the game. My plan to (slowly) add more content to the game has not changed though, so stay tuned for future updates!
