It's a fun concept and the style is great, but it's not that meaty, content-wise. Getting to the end felt more like "Oh, that's it?" rather than a "Yay, I did it!". Like other people mentioned, it'd be great if there was more pushback and complexity, though the more relaxed feel definitely does have its merits, and ideally you could find a happy medium between the two.
I also think the resources could also have clearer icons. I thought the asteroid rock material was log, and wondered why I couldn't place down a cloudmaker for a while.
