Supraland Six Inches Under is a First-Person-Metroidvania. That means, you're in a gated world and the more abilities you gather, the more parts of the world you can access.

- Half of the player abilities are the same, the other half is new.
- The puzzles are simpler in the main path; hard puzzles are mostly optional.
- There is less combat and all enemy types are new.
- Much more optional content, a lot of it only accessible after the credits.
- Almost all music was tailor made for the game while the first Supraland was using inexpensive, licensed music.
- The credits roll a few hours earlier than in the first game but there is much more significant endgame content.

- "Six Inches Under" was a little sideproject that was established to introduce new dev team members to our tools and workflow. Essentially it's our preparation for the sequel to Supraland.
- While David Münnich made the first Supraland game pretty much alone, he had a smaller role in this one. The core team for this one had 6 people.
- Pretty much everyone on team built 1 or 2 regions of the game world and in that sense it is very experimental.
