Darkness of the royal family is the fifth level of the Present difficulty in the Genesis/Mega Drive port of Lemmings.
Strategy[]
Contain the crowd below the entrance by making the second Lemming a Blocker just to the left of where the lemmings drop. The first lemming proceeds as the Trailblazer. Walk up the ramp until the block row just beneath the steel. Bash through these blocks, build across the pixel gap in the middle, and continue bashing. Build to the Exit portal at the end of the Basher's tunnel.
100% strategy[]
Instead of using a Blocker to contain the crowd, make the first Lemming a Digger/Builder to dig deep enough that they can step to the right, but not step to the left. Have a Lemming climb, to become the Trailblazer. Build a starter bridge to assist in selecting a leftbound Lemming, when it comes time to release the crowd.
