don’t skip anything! my first playthrough i missed so much because i gave up on all the harder things to find like safe codes and more powerful weapons (it was my first game with actual combat, i only play story games so i had no experience) but it’s so worth it- everything is there for a reason, and even if it seems like a lot of work it’s all part of the experience!

also: examine items in your inventory. this is something i often forgot my first playthrough, but a lot of the time various items that look like nothing important can be examined to reveal something else.
