So I've decided to just jump in because to be honest I'm making very little progress trying to puzzle out what to do in my head. I fired up UE4 4.22 since HTML5 support after that is no longer supported. I will look into getting enscriptem working with UE5 when UE5 comes out.
So first I created a blank project targeting mobile so hopefully it works with fewer dramas later as an android app or on a mobile browser.
I figured the first step should be writing the game engine or core. So what I'm going to do is make a simple text based engine that shows what's happening inside the game. I should be able to develop a graphical interface after that.
