Just downloaded it on steam, start it up, get a black screen with sound playing for the amazing animated intro I'm now missing out on, then get to the start adventure screen, followed by another black screen with very dramatic music, then dropped into a battle with characters who aren't ajna, but I can see it.
So I guess I'm having issues with video/cutscene playback as it's just a black screen whenever there's a video or an event with special art, but the dialogue names and text were still visible.
so when i played the game, i got to that very early scene with ajna's dad and dhar and saw nothing but words on the screen and looking at a youtube video indicates its pretty important to see what's happening, so i'm kinda stuck not playing until i figure it out or it gets patched.
i think its related to old nvidia cards, but that's just a guess.
