I don't think it sold that great to make a sequel. However if you really liked it I would suggest taking a look at Nausicaa of the Valley of the Wind which I feel was a strong inspiration for the game. Nausicaa has an anime movie and manga series. I preferred the manga better but it is a bit longer and the story goes in some strange directions.

Does anyone know if there are plans to make a sequel? I really liked both the story and the mechanics.

Same here - would love to see more. This game is underrated and deserves more attention. A sequel would be great.

Doubt it given the devs haven't even released an update to improve controls on PC, no mouse support is a really hard sell even though the game is quite good otherwise.
