Astraware's port of side-scrolling shooter Platypus [App Store] just landed in the App Store.
Based on the cult Mac classic from Idigicon, Platypus is a fast, fun side-scrolling arcade shooter with a unique difference – every tree, cloud, ship, and enemy was created from modelling clay - so explosions don’t bang, they splat!
Quite literally, every element of the game is said to be "made from clay and photographed using a digital camera." The game offers both accelerometer and touch-based controls.
Astraware has recently posted an updated video of gameplay that looks fun:
