Rovio, the makers of the record-breaking mobile franchise Angry Birds, has announced its upcoming title: Amazing Alex. The game is based on Casey's Contraptions, which Rovio has acquired.

Snappy Touch and Mystery Coconut developed Casey's Contraptions. The company teased on May 9 that the a new Casey's Contraptions title was in the works, after announcing Angry Birds has reached a billion downloads.

"Working with Noel [Llopis, Snappy Touch founder] and Miguel [A. Friginal, Mystery Coconut founder] has been fantastic, and this is a game that we all fell in love with from the first play.

"The gameplay is a perfect fit in our arsenal with its approachable, fun and highly addictive take on the physics puzzle genre. We are currently reworking the title to enhance it, and getting ready to re-introduce it in a true 'expect the unexpected' Rovio style launch to an even larger audience," Rovio's Vice President of franchise development, Ville Heijari, told Gamasutra.

The original Casey's Contraptions iPad title has been removed from the App Store. The game is launching this summer, initially on iOS and Android and further platforms will receive the game "rapidly" thereafter.

"The quality pressure is high. We want to maintain the high standard Angry Birds fans have to come to enjoy," Rovio CEO Mikael Hed told Finland's national television company in an interview.

The news on May 9, when Rovio announced Angry Birds has been downloaded a billion time, and teased the release, comes alongside the company opening a new studio in Sweden and acquiring Shattered Horizon developer Futuremark. It hasn't purchased Snappy Touch or Mystery Coconut.

"I'm still very much an independent developer, and I've been working on prototypes for my next game full time for the last few months," Snappy Touch's Noel Llopis also told Gamasutra.

Casey's Contraptions was released to critical acclaim in 2011. It's built on the open-source Box2D physics engine, like Angry Birds. Llopis and Friginal announced an iOS version of Contraptions, but haven't released one. That could be due to the acquisition of the IP.
