This should not be an immediate problem, and you should have no trouble actually running the game, assuming you have appropriate devices to test your iOS and Android variations. Just as different games have different system requirements, you will definetly need a better computer if you intend to work on more complex games. Note that there is a difference between your hardware running the software and running the software as required to make games.

In fact, the hardware requirements are fairly loose, and you should find support in any current or future generation Macintosh. Actually, the base system requirements for developing with Unity, Cocos2d-x and GameSalad are quite minimal, and are just within the system specifications advertised of the Mac Mini.
