Wow! This game rocks! ...and bricks, and logs, and water buckets! I love the mixing of story and resource-gathering. I must know what happens next and how the human from the beginning figures in. So I hope you create more! Two things of note: sometimes a resource appears yellow but produces the same thing as the normal colored one. It mostly happens to mineral rocks, trees, logs, and sand piles. Is that a bug? Lastly, I found a secret... but 10,000 energy for a stick?! I made/recycled all those watches for A STICK?!!! (O_O) 
EDIT: It IS a lovely stick though.
The sign probably should've been my warning I guess. I thought it might have produced a special item and unlocked the last slot for the recycler...
EDIT: The yellow/gold colored versions of objects do indeed produce more resources. I didn't pay enough attention to that in my first playthrough. They are bonuses not bugs. Hey, what do you expect from someone who would pay 10,000 energy for a stick? :D
