This was very good. I liked how the story was presented and I got really hooked by the midpoint and really wanted to see the end.
I would cut some of the repetition from the game, I know it's part of the narrative but it wasn't fun as a gameplay mechanic. I would find some other way to show that every day was the same without having to click through the same dialogue over and over.
Top notch narrative and artwork. Good job!
