I actually grabbed it alongside the soundtrack the last time it was free, and I'm glad because the music is great.

Some feedback: 

• I wish there was an option to adjust text skipping. I read fast, but sometimes it would skip a little unexpectedly so I had to pay close attention to the screen during dialogues. 
• Walking around the fjords was a little jarring with how quickly you traverse seemingly huge distances and the perspective. While I'm glad I didn't have to spend 5 minutes trawling through a scenic countryside, it felt a little odd. I feel like some distances could be shorter or a few screens skipped.
• Other users didn't like how easy the puzzles were, but I think they felt just right - I don't like moon logic in adventure games. My only complaint here is the final confrontation - It took me a while to notice that the two dialogue options changed how high you'd end up. If I had to think of a suggestion there, it would help if you had more time to do something as you're hanging.

Other than that, I have to restate how much I enjoyed it! I was really sure that we'd Ruth's mother on the ship somewhere or at least have her mentioned. I also hope that the blue space Hindu picked up the spare dilithium salt crystal on their way back ;)
