Umm...
As I read the description, I was expecting a game with flawless physics. As I started the first level, I threw the boomerang, expecting it to return to me. It didn't. As I progressed through the levels, I became increasingly confused about how to throw the boomerang. Sometimes it went left for no reason, sometimes it flew off without returning, and sometimes it actually came back. I think that this game has a good concept, but it desperately needs a physics makeover.
