The Lost Artifact

Our building is known for the magical portals that open here every now and then. We can create these portals using an old artifact, but this artifact is getting weaker and is starting to lose its power. We did some research and found out that there is a second artifact that was lost somewhere on an island far away. Can you find it before it's too late?

Please note! The artifact is hidden somewhere deep in the jungle of the island. To reach it, you will have to travel in the DARK, and also crawl or duck occasionally.
