Dripping with vibes, I really like the art, the tone and the early explorations - going out into the fog just watching the radar and panicking to get back in time. On the second mission I made it back with about 3 seconds to spare (I'm not sure if I would have had to restart the whole game if I failed). I enjoyed the third mission which you could cheese by throwing both cannisters off the mountain.
I did find the gameplay got quite tedious by the second mission - having to walk such a long way back and forth carrying cannisters, and I was about ready to give up by the third (knowing there would be two more), but it ended after the third so I don't think the game overstayed it's welcome too much (I just would have cut down the second level a bit).
I was a bit confused by what happened at the end but I won't discuss it here in case it spoils somebody.
