Algodoo

Based on "Portal Purgatory" from "Marbles On Stream". Which of the 26 marbles will complete this brutally difficult course before anyone else?

NOTE: While in the original, a miss means the death of the marble, in this version, it just means a setback. You're more than welcome to edit the surrounding teleporter into a kill box if you wish, but do so in the knowledge that you might not get a single winner. Don't delete the boxes to the right of the teleporter at all, those control various scripts that are vital to the functioning of the course.
