Best license to have for Kongregate game

So I'm creating a Unity 2D game, and I want to know what kind of license I should have in order to post to Kongregate, Google Play, Steam, etc.

I'm seeing licenses on github, (Apache License 2.0, GNU General Public License v3.0, MIT License, etc) but I'm not sure what to put the game under in order to distribute the game over multiple marketplaces and still keep the game in my own hands (ie no one steals the code and redistributes the game elsewhere).

Any information on this would be very helpful.

Thank you.
