Indie Game: Sunder Islands
This game had an interview read here.
You are sent to an alien planet with the mission to extract enormous chunks of resources to your mothership, waiting in outer space. This is not an easy task though, due to the bizarre geographical structure or rather missing structure and hostile environment.
The only solid objects inhabited by this gas planet are floating islands, which makes the crossing tricky without bridges and flying vehicles. For that reason, you have a helping tool that can build physically based structures like platforms and bridges to get you to higher terrain or far away floating islands.
