From the developer:
UnnyWorld is a strategy game with the action taking place in outer space. You have the chance to evolve your planet as you want. You can upgrade buildings, improve defense, and hire monsters to protect the planet from other players. Or, you can take your sword and use a magic ship to raid other planets.
You may want to check out more Mac applications, such as Thief 2X, Ranch Rush 2 Collector's Edition or Jean's Boutique 2, which might be similar to UnnyWorld.
