At first I thought it would be a game I download and play once and then delete it, I was wrong. It is very fun and hard, the graphics are great for a mobile game. However I keep looking up instead of moving forward. Overall it is a great game. Feels like I’m playing an old Xbox 360 indie survival game. Please up date this game more, when I enter the place that takes me underground it always freezes and the game crashes. Please update!
