Reallly beautiful game with interesting mechanics. Really impressed with the overall design. The game isn't challenging. While it could be considered a puzzle game, there was really only one spot where I was puzzled for about a minute or two (thinking maybe there was a bug) before I realized what it wanted me to do, and I felt silly afterwards because it was pretty obvious in retrospect. And the only time I died was near the end where it wasn't clear how to survive the final section, but it wasn't bad. This is a really great example of a well mechanic introduction. There was never any "tutorial" it just taught each of the mechanics in a simple and intuitive way. The only frustrating part was how much fuel I stockpiled, the game definitely gives you way more than you need, by the end I was tripping over it and had it squirreled away everywhere on my ship. It's possible to waste the fuel or miss it, so I'm guessing it's just trying to be sure you never run out.
