Don't Look Back without the time-limit gadget. The time limit's purpose was that nobody turns; let's aim for the purpose, not the means.
The exit sits in a box with only a small opening. The box turns uninterrupted builders. An uninterrupted builder was too slow in the old version, and turning fits the level's spirit.
Agree how Don't Look back is streamlined, without any hard trick, good for Cunning.
