Canabalt, $0.99 - After raising more than $30,000 for the Child's Play Charity as part of the Indie iPhone Game Sale over the holidays, developer Semi Secret decided to celebrate by making their game Canabalt open source for people to tinker around with or use to create their own game (with limitations, of course). The Canabalt code that was released as open source was an even more up to date version of the game than what was currently in the App Store. Now this improved version has become available as an update for iOS owners of the game.

The update features Retina Display graphics and 60fps on iPad and 4th generation devices, Game Center integration for high scores, and other performance optimizations and fixes. Significantly, this update appears to have finally fixed the long standing problem of stuttering and choppiness on 3rd generation devices. Canabalt running at a rock solid 60fps with Retina Display graphics is a sight to behold, and the game is now crisper and smoother than I ever imagined it could be. Game Center integration is nice for comparing scores with my buddies, but sadly there are no achievements included at this time.

With so many running games available, it had been a while since I fired up Canabalt. But playing it today to check out the new features reminded me why it's one of the best in the genre. The simplicity and elegance is unmatched, and my goodness do I love the music. If you own a copy of Canabalt make sure to grab the latest update, and if you have yet to pick it up it's currently still on sale for just 99�.
