I really dig the contrast between the (beautiful) black/white scribbles of your daily life and the colorful plant, it evokes the feeling of “the one part of the day that keeps you going” quite well.
I love the one-sided dialogue as well. So much that is transported in the references and answers of a conversation that makes it much more natural and emotional than if everything was spelled out!
I know that “handling the plant wrong” is not an option for this type of game, but I’d have loved to interact with this centerpiece more. A more involved and haptic way of telling what the plant needs and administering the treatment would be a great addition, if you plan to keep working on this.
