Katta-Strophe

Katta-Strophe (pronounced Kat-ah-Stroaf) is a puzzle game where you pick up objects and place them somewhere else. It sounds simple, but there's actually a lot more to it...

Depicted above. 

As stated above, you can pick up and place down objects. BUT, you can only place down an object on it's matching destination tile (the blue ones). If you have an object held (you can only hold one at a time), you can push other objects that have not yet reached their destination, provided the adjacent tile is empty.

...and that's a fact!
