NUTS is one of the more unique games that's available on Apple Arcade. It's a game about observing nature and the life of squirrels. It has a bit of Firewatch vibes with its graphical presentation and such as well as the first-person point of view throughout. 

You're a researcher hired to take photos of squirrels each day. In short, you're a photographer or videographer of sorts too as much as you are a researcher. You then send the pictures over to your boss, Nina, a veteran researcher to evaluate your findings. 

You take pictures during the day by placing your cameras in different locations. And then, at night, you review your footage until you see a squirrel in action. From there, you shoot your image(s) over to Nina. Here are a few other things to know about NUTS.
