Great to hear you're enjoying the currently available content! As for your specific point, it's true that some scenes are currently only black screens. This is done as a way of trying to show the player that there will eventually be artwork for those scenes, but that it's not there yet. Having said that, there should be particular scenes where there is art involving Sarah/Varga, currently in this version.
So as development continues, over time, those black screens should slowly become more and more rare.
And as for Varga, don't worry, his character is very honest and he's exactly what he pretends to be. What you see is what you get with him.
Hope you'll stay a fan as development continues!

Oh ok :) Yes playing further I found them! I'm surprised at how different the paths can be, in a good way! I was so sad when I got to Atillas end path. The thief was one of my favs though! Can't wait to see where his will go. Also Jaeid caught my interest! Just a phenomenal job so far! Keep it up :D
