I downloaded the game , but it's very laggy while I play it. Like when I jump I'm in the air for 2-3 seconds. If you know how to fix it I would love to hear. Other than that this game is awesome! I love the Little Nightmares feeling
Sad to hear you are having troubles running the game, i am not sure what causes it. It depends on your computer. Try turning of any other software which may be runing in the background!
