Hey there! Thanks for giving it a go. The goal is to stay near the light trail and find 3 memories. Unfortunately, this build is broken, so the lighting makes it really difficult to see the visual guides that would have helped you figure that out. In addition, it appears that the same shader having trouble with the lights is also causing the bridge "blockages" to not properly appear. E is only for when you are hovering over things that allow you to interact with them.
