Any update on this? I haven't tried UE yet, but I've been looking through loads of articles/videos and it does look very, very impressive. Plus we all know UE is much more polished (under the hood) than Unity.
I'm looking to try out UE next month, and the open sourcesness of UE is a huge plus. Like unikronsoftware said, if there's bugs, they can get fixed quicker! That means quicker released of TK2d, quicker bug fixes, and making TK2D better, quicker. Remember how long we had to deal with the camera bug? It was months!
I'm all for an UE version, and I hope unikronsoftware decides this is a big, big deal. As I'm sure people will begin to migrate to UE from Unity.
