Demo length, content and save scope
Quick answer
The documented demo is an opening slice, typically described as roughly one to three hours depending on exploration.

What the demo includes
The route begins near a shore camp, continues through ruins and a burial site, then reaches the shrine encounter. Optional gear, secrets and completion objectives can substantially change how long a first visit takes. A fast completion is not a realistic budget for a player learning the controls.
How to plan a session
Allow time to learn power-meter combat and inspect side routes instead of using a speedrun as an expectation. If your purpose is a performance check, test the encounters and settings that matter on your own machine. If your purpose is completion, inspect the journal and optional achievement tasks as well as the main route.
Demo versus retail
The demo is a separate application. Retail walkthroughs continue into movement upgrades and areas outside that slice. Check the version before interpreting an inaccessible gap as a missed technique. Save-transfer behavior is not established by this reference, so preserve progress rather than assuming that the full game will import it.
