Appreciate the positive words! It has been quite an adventure to get the game this far considering it is my first game to develop ever.
As far as a version for the mac. I currently do not own a Mac computer therefore I cannot build for Macs from the Unreal Engine. Further into development I plan on acquiring one but at the present moment there will not be a Mac version for a while.
I will definitely check out Game Development World Championship tonight. Sounds like it would be very interesting and quite fun. Cheers!
