Demiforce has released an update to its acclaimed Trism puzzle game for the iPhone and iPod touch, adding native iPad support and fixing some iOS 4 related problems. First released in July 2008, Trism was the first Match-3 puzzle game to make use of the iPhone’s accelerometer feature and was a runaway success in its category. Trism 1.5 maintains the same game play and features as the original with five game modes, online scoring and 22 in-game achievements that can be collected. The update fixes stability problems that some users have experienced with iOS 4.0, adds native iPad support and provides code optimizations that should result in improved battery life. Trism 1.5 is available from the App Store for $3 and is a free update for current users.
