In New Hope: Episode 4, Level 5 (level with 5 red lights on floor, grate on bottom with minkit downstairs on the right, and twist-raising platform). We can't figure out how to get the bridge to slide open? We only have 4 characters so we can't have someone stand on all the red blocks at the same time. How can we open the bridge to slide open so that we can pull the last level and open the door? Help!
