I spent about 30 hours reverse-engineering the code of Silksong, one of the most successful Unity games ever. And found some genuinely impressive (and aggressive) optimizations.

Highlights:

• Movement Code Breakdown: I broke down the exact frame-windows for Coyote Time and Input Buffering that make the platforming feel so responsive. The Elegance of Silksong movement as is :]
• Hidden "Demo" Mode: There’s a left-over IsExhibitionMode check. With a small patch, you can actually boot the Gamescom demo version from the retail files.
• Dev cheats, Debug view, Performance overlay, etc: We recover and re-enable everything to see how it was used by the developers.
• Performance: Team Cherry implemented a Manual Garbage Collector and a custom reflection-to-delegate compiler. It’s a 100x speed boost over standard Unity methods.
• Much, much more in the video.
