This game is really interesting. By the author of Little Blue Men and Anchorhead, it is intended for children and comes with a great set of supplementary materials.
There is a sort of tedious opening with a ton of hand-holding before it opens up to a wide world. I enjoyed the islands, especially the junk and dark islands.
I felt like the author was holding back a bit on some descriptions that could have been made biting and/or sad. But the sparseness was fun.
One of the last islands seemed like a big buildup to an anticlimax.
Overall, I have to say I enjoyed it, because I couldn't put it down, and couldn't wait all the next day to play more. So that's a good sign!
One thing that can seemingly lock you out of victory:
(Spoiler - click to show)The icefruit seed doesn't respawn correctly.
So I suggest that, to be safe, you save (Spoiler - click to show)before using it.
You'll know you did it right if (Spoiler - click to show)Something dramatic happens.
