The update adds new music tracks and pause functionality, as well as moves the "punch" button to the right side. The default difficulty setting is also lower. All the changes were made with feedback from users, with the exception of the name: that was due to an unspecified copyright issue.
Our own Mike Schramm noted the app as one of his favorites for the iPhone.
The updated Moto Chaser is now $5.99 for new users, and free for registered users. Freeverse lowered the price from $9.99. It's available in the App Store.
