Joe Danger Touch has just gotten its largest update so far, along with a price cut and new downloadable characters to boot. The 1.0.3 update adds 21 new stages, along with a new mode offering daily challenges.

The app (via Joystiq) has been discounted to 99 cents for a limited time, a 66% discount from its usual price. The update boasts five new characters, and an improved Laboratory. A new Calendar Tour mode offers daily challenges. If you finish all of the daily challenges in a given week, you'll get a harder set the next week, with coin bonuses as the prize for your diligence.
