Not too bad! Like Outbound Flight I am now interested and want to see more world-building, more ambiance in general. I didn't mind the "take a flight" or linearity as a clear tutorial for the alpha, but I'm sure it can be made deeper.
I also wanted to see what kind of bonus there was for going above and beyond. I know it's silly for a demo, but the little rewards drag me in.
There is one moment where the voice actress of Darma and the text don't line up. Again it's a small thing, but I see this in indie games quite a bit.
I hope this helps.
