Played through this demo just now and really enjoyed it. I like the concept, the initial depictions of the world, and the way the prose communicates the physicality of being on a long journey. I love the descriptions and interactions with the peninsula's wildlife and the thought given to how this society operates. I know the music is meant to be temporary but it fits the style of the game quite well. The attitude system is also an interesting concept.
I have a few comments:
-As others have pointed out, there are many, many grammar and spelling errors. However, they don't interfere with comprehension for the most part, so I didn't feel like they were a huge deal at this stage. There was one exception, though: the text minigame prompt being "What are you looking for" and not "What will you look at" or something similar made me think I needed some specific goal or item in mind. The initial answer being "floor" doesn't make sense in that context (the floor is right there, why do I need to look for it?)
-The conversation with the soldiers felt less like a conversation and more like reading several encyclopedia entries. I understand the need to communicate details of the world to the player, but I think they should be spaced apart more and introduced more naturally, especially because I think this world is an interesting place.
-Most of the dialogue choices with the soldiers boiled down to "be an asshole" vs "don't be an asshole", which is never that compelling in video games. I think it'd be more interesting if the conversation was based around the two groups' lack of initial trust in each other, which they could then develop... or not. As is, there didn't seem to be a reason for me to ever not be polite.
