My text didn't auto-advance at first (only first leter would show up). I restarded the game and after that it was going nicely, but I noticed a bunch of typos in the text.
I've had Zuhra get injured but then the burial cutscene played and she was gone from my squad, replaced by a second (You). I then walked around the town and noticed some more bugs, like speech bubbles being shown only partially, like "I'm f", and I got (You) to -100% hunger but he didn't die. I eventually found the starting town, and when I entered it the cutscene played again, and I had 2 Katyas, and after beating this scenario the Zuhra death cutscene played again (even though she didn't die this time).
I also had one NPC freak out at the end of the stage you meet up with Katya and Zuhra, his legs were still, but the torso would rotate around trying to target the group members.
It'd be nice if there was a hotkey to focus camera on a party member (maybe pressing the number twice, or when they're selected already it'll ).
It's very nice you can escape before picking up your companions, but dialogue doesn't reflect that and still uses plural.
Aside from this issues, and demo being pretty short, I really liked it. Good job.
