It’s pretty short at around 4-5 hours. I found the gameplay was excellent. I found difficulty was just right. It never got too frustrating, but I always felt challenged. It never got boring, and it was really fun to see how the environment kept changing as the game progressed. It also does a really good job of doing story telling through gameplay. I find a lot of games tend to have a game portion and a story portion. Here, they managed to blend both story telling and the game completely seamlessly. Highly recommend if you enjoy this genre of a game.
