Seems like an interesting demo, though, unfortunately, I was not able to play it until the end. My sleep deprived brain was screaming at me to go to sleep 
The setting and the flow of the game looks great to me, however I found multiple spelling errors at the first 10 pages of the story and so on. Something like misplaced words: to - too, be - bee; and etc. Nothing serious. Also, when we meet Captain Van [something, sorry I’m just terrible with names], the pronounces keep switching back and forth.
This is just a small example of minor mistakes, nothing big because I haven’t progressed further at this point. Hope to get back to resuming my playthrough and possibly send some more feedback once I have my rest.
Anyways, good luck with the game!
