Quick answer
Find the complete bright line and both of its endpoints before opening the crossing. Compare the linked recording for the release order, keeping the red character away while the line crosses its intended route. A tall black frame encloses an upper red ball and right-side green creatures, with a vertical glowing beam on the left, a rock above and a tilted wooden bar below.

Step-by-step
Locate the red ball and every green creature before cutting. Keep the starting support until the route below is ready.
Find the complete bright line and both of its endpoints before opening the crossing. Compare the linked recording for the release order, keeping the red character away while the line crosses its intended route.
Prepare the boulder route separately from the ball route. Open only the support needed to move the boulder into its useful position.
Leave room for the wooden plank to change its angle. Remove sand around the moving end without trapping it against an untouched wall.
Check the full target route after the last movement, including pockets above the final drop. If a creature remains, identify the earliest turn that missed it and change that local approach on the next attempt.
Tips
- Check the bright line before each release, including the return path. A route that is safe in one visible frame can change when surrounding objects move.
- Leave the rock’s support until its destination is ready. Removing it early can occupy the same narrow landing needed by the red character.
- Watch both ends of the wooden piece. Clearing one end while trapping the other can prevent the change of angle shown in the recording.
Common mistakes
- Opening the final outlet before checking higher target pockets can leave a creature above the character with no route back. Inspect the side entrances before making that irreversible drop.
- Removing several supports in one swipe makes the release order unpredictable. When a moving piece occupies the route, wait for it to settle before changing nearby sand.
Frequently asked questions
What should I check at the bright-line crossing?
A tall black frame encloses an upper red ball and right-side green creatures, with a vertical glowing beam on the left, a rock above and a tilted wooden bar below. The crossing depends on the visible line and the positions of nearby objects. Compare the moment just before release in the recording. If your board differs, hold the starting support instead of assuming the same crossing is safe.
How do I keep the loose rock from blocking the route?
A loose rock can settle across a passage that previously looked open. Check where it will stop relative to the next target, then separate its release from the red character’s arrival. This is a timing problem as well as a tunnel-shape problem.
What space does the wooden piece need?
A wooden piece may lean into the same entrance the character needs. Compare both ends and the remaining support in the video. Clear a controlled movement area first, then check whether the resulting angle connects to the next pocket.
