Are you a Cult Of The Lamb fan? ;) It recalls the cozy mechanics of its camp building without all the stressful hassle of sickness and decay. Besides, reducing action to be present nearby, rather than constantly clicking, makes it less compulsive and allows the used to still "flow" around the map being consequential. Another interesting point I see is that you saved the mouse click for the most meaningful thing you can do, which is building. And because building is embedded within a sort of evolution mechanic (every time you need different materials and depending on what you build you can advance on way or another), you get to imprint the sense of progression that tells the player that he is going somewhere to an end, not wasting time by completing loop tasks.
The are is just amazing, and the sounds are great as well. Overall, I think you got to make a peaceful cute experience ;)
