Yes, but tapir has to stay, so the directory should too
Here's my solution to Laser Deathroom, and 100% saved on Wreck of the Hesperus.
EDIT: Two more solutions to Lix Ferenda: 72/80 saved with a conventional route, and 73/80 by platform spamming. I'd still like to have a go at making a hard version of this level, if it's okay with you. If you want to stick with the current terrain, but want to force the player to use the bottom-right as you said you originally intended, it looks like you'll have to require 72 and reduce the number of platformers.
