Is there any way to optimize and reduce the package size?

I’m working on a 2D physics game using cocos2dx and box2d (and I use Level helper and sprite helper also). Now the project is coming to the end. But I found that the package size is above 200M now( it has been built on release version, and compressed to .zip). I think this size is too big. Is there any way to reduce the size?
Thanks in advance.

200mb is a lot!
You need to reduce your graphics\sounds, I don’t think the binaries are that meaningful.
