Thanks for the feedback.
Theme is indeed a bit too subtle. It is explained in the outro, but sadly we have a bug introduced in the last minutes, which results in not playing the outro. The theme is applied in the sense of "you bring something with you that seems less (plant), but is in a lot more need than we think (at least on a deserted earth).
You are pointing out some things that we overlooked. Subtitles have to be considered and also different colors on winds would have been helpful to indicate if the boost you or drag you down.
