I think they're talking about Research into Corruption, which had much higher quality in terms of colloquial writing, but was a bit more irreverent/less sappy. I'm not 100% on the timeline, but that game I think was originally developed by Boomatica, then taken over at some point early in the development by DrSmith, so I'm not sure how much of the tone of the story belongs to who, and then it was abandoned and I think will be taken over by Dark Coven, who currently works with Nun Ya if you want to get a sense of their writing style.
I've been told the writing in this game improves at higher levels; I got to about the end of level 5/beginning of level 6 with I think 20 or so hours while reading almost every single line without skipping and frankly it got insufferable so I've not touched it for a few months. I want to get back into it so I can write a review giving what I think will be a fair take. I was disappointed by the shift in tone switching from RIC to this, but that's a subjective take and I would never knock points off a game for that; the writing style is infinitely more of a disappointment--the speech is somewhat similar but the verbal ticks in this game are greatly increased, there's less snarky humor, and the repetitiveness is honestly headache inducing at times. But the core of what's there is good so I do want to keep up with the game until it's done.
