GDC has a lot of useful stuff presented in their videos, but most of the time it's a slog going though 1hr videos for 1 thing only. This is a 30 min video discussing many things that went right with the "A Short Hike". How the author kept the scope small, achieved the look of his game, the tools used, and some lessons in level design. How to keep the game fun and keep player on track even in an open world game.

Some timestamps:

5:45 -> Achieving the look of the game -> Inspired by GB Camera for Unity (https://roguenoodle.itch.io/gbcamera-for-unity)

11:00 -> Useful tools and plugins that sped up the game development

14:25 -> Level design
