My first play through I almost immediately found an artifact and then was trying to figure out if there was a pause button and exited by accident. Second playthrough, I wandered around for like 10 minutes without finding an artifact nor the gorilla (I had a camera drift issue that time that caused me to constantly turn slightly right so that contributed to being lost). I finally found an artifact and then got immediately killed by the gorilla. It was definitely spooky though. Good job!
