Great job, wow! I'm amazed by how polished this game is, from the controls panel to the language selection, from the little animation of the humans to the rain particle system. You put time and efforts in this, and it can be seen all :)
From a gameplay perspective, I found it quite relaxing: it was nice to water plants and watch them grow, but mostly it was satisfying to gather resources, making me wanting to play more!
The only concern I have is about the little balancing between mechanics: I was unsure about how my actions were affecting the game, and the humans behaviour was not always clear. I rained on some of them and they ran away, then they stopped working, and in the end they cut the vines - which I thought it was only an obstacle. While it was always clear to me that I had to produce resources (and somehow I managed to do that), I quite missed the cause-consequences chain of how it happened. That is not to say that something's broken or anything, I just thought it may be nice to attach my experience to my comment.
Again - great submission, congrats! :)
