Yes i read it, portable on another game engine, problem witch video, developer do other game.
You don't use raw languga (like C++, C#, Java) you use game engin it's mean you don't need create full funktional out zero.
And no need create hard system moving hero or shoting, just show text and cange images, if game whas be have more than 1 ends, all PC choise can be realize like massive bool trigger or byte.
Okey display video in game can be (i heve this problem also too
)
In internet can be foun much implementation examples and source code for free using.
I don't tell game or you team is bad, i told 3 years it's super long time for so short game game doesn't develop at all
I whanna see progres!
