As of November 15, 2015 I'm using multiple engines/sources to make Open Dimension Portals: Alpha Possible. Why you may ask? Due to graphics enhancements and flexibility of Unity & UE4 vs the long, non-royality, simpily-coded engine that I'm creating.
I'll determine which one I'll continue to through out the whole game. Progress will be shown on my Youtube Channel,IndieDB and/or Tumblr.
