In reading each of these stories, I've been blown away by the talent here, and moved, in a way, to comment on these pieces. Hopefully each of you find my criticism useful.
Picking up where I left off:
Mohabot "The Stranded Survivor"
This one was a trip, trying to figure out how he was castaway, and what (if any) the house's intentions were. I think a lot of this ambiguity came from how short it was. I think you could take more time to develop the character, especially since most 'survivor' stories don't include a house washing to shore.
A very original twist on the desert island scheme, I just wish I knew more about the protagonist and the house. Keep on writing, I want to see where you go from here!
