Start with the center, then move outward
Begin at the campfire because it teaches the most important interactions in the smallest area. Pick up a marshmallow stick, test the edge of the flame, add a stick to the fire if the interaction appears available, and scan the logs before moving away. This gives you early progress toward the marshmallow badge and prevents the common mistake of ignoring the central props.
After the fire, follow the stream and beach before going to the forest. The water movement can carry your cursor across hidden pickup spots, while the beach is the natural home for several seashell checks. If the screen is crowded, move in short strokes and wait for other cursors to drift away from tight corners.
