Analyzing PolyMarsDev's Shift to Dedicated Puzzle Design Long-Form

I've been tracking the channel's performance since the transition from purely action-focused dev logs (like the 'Gravitational Flux' series) to the deeper dives into puzzle mechanics, such as the recent video on non-linear progression loops. Statistically, the engagement rate on the critique/analysis videos seems significantly higher, suggesting the audience values the theoretical aspect of game design over just witnessing the coding process. Does anyone have insight into the production differences? The editing tempo is notably more deliberate in the puzzle analyses, which complements the serious subject matter effectively. I wonder if this approach is more sustainable than the high-tempo action sequences.
