hello I’m looking for a old game that markiplier played

Idk if this is the right subreddit as I got suggested this but I'm looking for a really old games that markiplier was playing. It was a survival game where the person in game is a scientist and lost his memory and has to survive for at least 3000 seconds or so? I can't remember but it involved a monkey and other creatures. If this isn't the correct subreddit delete my post thank you!
