Lix was part of a study about learning

[Forestidia86]

I don't know if it was talked about already:

Some time ago I stumbled into that google books snippet:

The text parts available indicate that Lix was used in a study about learning, which I just found remarkable.

that is remarkable

how comes Simon always gets all the fame?

I haven't read it all yet so I wonder exactly why the picked this: it's not well known but based on a well known game. Thought from my skimming it looked like perhaps they wanted an open sourced game that was easy to modify.

how comes Simon always gets all the fame?

Because of his name. The Simon effect is an ancient psychological phenomenon .

Wow, interesting find! I knew this paper existed, but had not found it before. Thanks for fishing it from the internet!

I discussed this research project around 2012 with the scientists. Singleplayer and multiplayer work by recording the bare minimum to recreate solutions: You save/send only your assignments, everything else follows from the deterministic physics.  The scientists weren't C++ developers, but figured out enough of the code and the replay format to extend Lix with player monitoring: They monitored level restarts and level progress.

They chose Lix because of its self-contained levels, to study a well-defined small section of the game with many people. I was really happy about their choice, offered to answer any questions about the code, and answered their survey about game design and learning.

Never thought I'd get referenced by a psychology paper earlier than by math papers. Cool thing!

That is quite cool they picked your one one for the study Simon. I noticed they have included a screenshot of the lix game as well, might be more screenshots, haven't checked that one yet. That's kind of cool.

On this site seems to be the data gathered for the study.

In this PhD-thesis Lix seems to have played a big part as well. It's by one of the study scientists.
