Not quite puzzles, but since someone else mentioned Schemaverse, I have made a similar but Elite inspired SQL-game called Datastar [1]. It features a simulated economy with traders and miners, and the goal is to make as much money as possible. Everything is done via SQL (or other PostgreSQL features), and the player need to make and manage a database of information about the planets and their economies.

I teach uni. couses on databases and made the game for my student to give them a more self-driven way to learn SQL.

I'm trying this out right now, since I'm writing a database exam on thursday. Is there a way to provide feedback?

I feel like the game has a lot of potential but some stuff feels kinda painful.

Like figuring out all constants for example.

Feedback would be great, thank you! For concrete pains I welcome making issues on the repo. Otherwise you could comment here or DM me :) Also note that the game is far from finished, with lots of remainong TODOs.

Regarding constants, which are you thinking of?

I don't have my Gitlab credentials set up on my Laptop but I'll open an issue in the Gitlab Repo once I'm finished with my exams.
