This was really well executed, especially visually. I wish there had been some music, or maybe some more ambient sound that would help further set the tone, though.
It also felt like I always had plenty of time to collect all the resources in an area and there were never any real threats. It would have been cool if I had been more to make harder decisions and/or take more risks. For example, maybe larger amounts of resources were behind traps or a difficult to navigate area, making it likely that you would not get back in time if you failed to get them cleanly.
Regardless, the gameplay was smooth and the whole thing felt really polished. Great job!
