They should make a really epic movie for this game and have markiplier as the main character.
Very scary. Almost soiled my trousers when the wall from the Roblox game "Get crushed by a speeding wall" showed up. Terrifying atmosphere. Only downside is that the game was in first person so I couldn't see Markiplier's face.
This is a pretty cool game, would be lowkey cool if they made a movie about it. Maybe have a Youtuber make it, perhaps even Markiplier.
Creepy as hell and triggering my underwater phobia even when you don't actually see the "water". Navigating the submarine purely with a map and co-ordinates is a lot of fun and the story it tells is very minimal, but done extremely well. Great little game. Very excited to go see the movie 👍
I played and watched the game and the movie on the same day. They are both good. Keep in mind that the movie is indie, not Hollywood. It has gained popularity due to Markiplier. Note that the game relies heavily on sound. I do not recommend them for Deaf/HoH people who rely on accessibility features.
