Really strong central hook with using different species as puzzle-solving tools, it creates a fun and intuitive connection between the game's mechanics and subject. There is also a strong emotional foundation that I feel will make the robot's journey feel much more meaningful without requiring a large amount of dialogue. The only thing that is concerning is the scope of the project, especially with each plant requiring its own interactions, animations, logic, and failure opportunities. I think a strong next step would be building a vertical slice around a couple of plants first , and once that's completed, start implementing others. I can't wait to see where the project goes!
