« Very good but very short game, I'm mostly worried how the movie will manage to drag this into 2hrs long. Edit: Guys I just watched the movie, it adapts the game pretty well actually and it didn't feel overly long!!! »👍 anonymous review · 2 h played592153« They should make a really epic movie for this game and have markiplier as the main character. »👍 anonymous review · 2 h played94181210« this game created new submarine,, out of my butt,,,, poop... because its scary... »👍 anonymous review · 2 h played312076« 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. »👍 anonymous review · 1 h played5321« 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. »👍 anonymous review · 2 h played611« hey markleplier, congrats on your movei. im glad youre having fun., much love, grandmom »👍 anonymous review · 0 h played311
« voyon don ces la marde comprend rien »👎 anonymous review · 0 h played« Très court, très facile, le concept est intéressant mais le jeu est assez creu. pour 6$ ça peut passer... »👎 anonymous review · 1 h played« I'm sorry, but I do not understand the hype for this game. Extremely tedious gameplay with very little payoff. That being said, I love the atmosphere and graphics. »👎 anonymous review · 1 h played« unbelievably overhyped. 2 hours of my life I will never get back. »👎 anonymous review · 2 h played« I'm sorry, $10 CAD for a one hour game with basically nothing happening in it, 0 replay value and one jump scare? Talk about ripoff. »👎 anonymous review · 1 h played« Market pliers Also, got the game as a present for my bday:D »👍 anonymous review · 1 h played311
