The gameplay is based on survival of the character that depends on solving situational puzzles. The difficulty to be best described is moderate. Some sequences if played with headphones on will surely make your heart skip a beat. The makers have put great thought into the creation of this dystopian world which scores higher on the immersive experience as compared to Limbo. I recommend headphones for the best experience and have already recommended this to my friends, its a solid game. Thank you, Playdead.
