I started by going along the northern edge of the space island, then down towards the Sword Grunt. When he began chasing me, I headed for the five south-pointing Arrowz, on a diagonal, until I was just below the Arrowz, left moved west and diagonally northeast to squash the first Grunt. Then I went straight for the central Arrow, and the Sword Grunt obligingly attacked directly toward the point of the Arrow, stepped onto it, and squashed number two. I went back toward the north and west, and came at Grunt #3 from above the Arrow; same result ... attacked from directly below, and was squashed when I stepped on the Arrow. I'll leave it to you to work out the rest.
I went through several of Bjarni's Custom Levelz yesterday (November 17, 2005) and created a version which gave cluez as to where the SecretTeleporterTriggerz are located. The original version is still available from Paul's Gruntz Page, and there is now a link to download my version as well.
I had to reverse ten (or so) logicz from leading east, to leading west, in order to reduce the width down to 40 tilez. I also moved four logicz from the bottom left to the top right, along with the tilez associated with them, to reduce the height to 67 tilez. I added in a Green Warp to move the two gruntz from bottom left to top right. I fixed a small error, where there were two Warp Letter 'W' , changing the second one reachable to Warp Letter 'A' . I trimmed away dozenz of Brickz logicz associated with unbreakable Brickz on the King's Fortress asteroid, and gave it a "more exciting" outline. Everything still workz as the Designer intended, but on a much smaller map. But BEWARE ... the Secret Switch timing is now less lenient ... the grunt has further to travel.
I do not intend to re-distribute this to the Gruntz Fanz ... use the download link, if you want to try out the smaller version.
