"We'd often see testers get stuck in rooms that had [Morph Ball] tunnel exits--they won't notice them. This resulted in putting big spotlights over those entrances to make them stand out as a path. Our testers often couldn't figure out how to get up to the bridge leading to the Arboretum. After they acquired the [Morph Ball] and returned to the Main Plaza in the Chozo Ruins they didn't notice the steps in the back to cross the bridge. Originally both back steps were nearly the same color. We changed them to different textures and improved lighting. Our next set of testers noticed it immediately."
