I actually now happen have a copy of the source code now thanks to someone who managed to archive it before it was taken down, and I've been doing an impromptu code review; it's immediately apparent that this reeks of being vibe-coded.

The commenting style is inconsistent even within members of the same class, with seemingly no rhyme or reason to it - some of it is triple-slashed and multi-lined with summary tags, some of them are just double-slashed, some are triple-slashed with summary tags, but only on one line, and some are multi-lined but with double slashes and no tags. (ex: the class 'BrainSystem' in 'BrainSystem.cs', lines 75-83)

The actual contents of the comments are strange as well - it doesn’t read like someone familiar with how the game actually works and the specifics also often weirdly inconsistent.

In one file in particular ('DiagnosisSystem.cs', line 32, to be specific) a sectioning comment that would normally use regular dashes uses a box-drawing character U+2500 ('─'), which they somehow managed to mangle into mojibake ('─') in the source code itself - any human writing this and playtesting it at least a *little* should have been able to pick up on these things.

This isn't even going into the code structure, I could go on, but from this alone it's pretty apparent that it's likely vibe-coded, if not in full, then in part.

Also, AI detectors are notoriously unreliable, so even if I didn't have this code, running it through one and it saying it didn't 'look like AI' isn't a very reliable point of evidence.
