Reading a level before building it.
An example notebook for level planning: routes, landmarks, player choices and the first greybox pass.

Start with the route
This template is a place to explain the intended player journey before discussing individual rooms. Write down the entrance, destination and choices along the way.
Make the decisions visible
Record where a player can see a landmark, find an alternative route or pause before a difficult encounter. A route sketch is often more useful here than a polished screenshot.
Build the smallest useful test
Use a greybox to test scale, visibility and traversal. Keep the first pass simple enough to discard.
Capture the revision
Explain what the test revealed and which part of the layout changed. Replace this example with a real sketch, a playtest observation and your own conclusions.
