I've been playing Paul Greasley's Under The Garden for most of the evening and it's superb. The game is set in a harsh, unpredictable outdoor environment, and the goal is to survive for as many days as you can. You can cut down trees for lumber to make fires, hunt animals for their meat, mine rocks for useful items and rebuild your small cabin in the heart of the countryside.
When you're out and about scavenging for useful items to help you survive, your stamina bar slowly drains, but when the weather is particularly bad, it drops at an alarming rate. However, standing next to a fire restores lost stamina, and exploring the wilderness while leaving yourself enough time to get home is a delicate balancing act.
Under the Garden has a wonderful atmosphere thanks to its stylised visuals and beautiful soundtrack, which tinkles away in the background as you desperately try to last for one more day. The game is free to download, and you can get it from here
