Wow, you nailed the feeling of "isolation" on an emotional level. I mean, what a life this guy's living! The constant dread of something falling out of balance was palpable, and yet all that effort was just to maintain a pretty sorry state of affairs. It made me think about my own life in ways I don't want to admit. I've never seen manually pulling water through a plant's veins as a game mechanic before, but it somehow felt very bleak, as did having to pluck thorns just to get something to eat. Loved the storybook illustration-like visuals and the moody music, all working together to set the tone. I think maybe the letters could've had less text and more frequency to parcel out the story over time, but it was an interesting idea to include a sort of diary. Also, this is a small nitpick, but I think your logotype for the game title doesn't really match the mood of the game itself (maybe it was meant ironically?). Overall, a unique take on the theme!
