An interesting concept and setting! I like the way the gameplay is delivered through a diary telling you what has happened, and then you make choices based on that and your resources.
I struggled a bit to understand what my choices were, what decisions I could make. The only thing I could figure out was whether or not we could go out that day, and if you used medicine or not? And I couldn't think of any reason not to use the medicine? What the consequences would be either way (assuming you'd die if you didn't take the medicine).
Last thing I'll say is there's a certain charm about the drawn art style :) especially contrasting with the bleak setting.
