This is John from InMotion Software (of "I Dig It" and "Dungeon Defense" fame). We are the developer for Monkey Quest: Thunderbow. Nickelodeon plans to release the game world-wide tonight. Stay tuned.
Thunderbow is an extension of Nickelodeon's MonkeyQuest.com MMO, for those of you familiar. Players can unlock exclusive weapons and gear to use in the MMO by playing Thunderbow.
This is strictly "unofficial," but the game itself could be described as a cross between Angry Birds, Fragger, and Worms with gratuitous explosions and tons of physics destruction, etc.
