Alternate titles include don't get stabbed, eaten or set on fire.
A survival roguelike game with perma death. That also contains lots of things that are going to kill you. I think the game is really good. They're still adding features even since the game has been out, but that also leads into one of the game's major problems. Back when there wasn't a lot of items in the game you could figure out things in some sort of reasonable fashion. That just isn't the case any more, you have different tiers of research station and you can come across things that you've never seen before within 5 minutes of starting a new world that you had never seen before even if you had been playing a separate game for hours on end.
While you can survive the first couple days, it unfortunately all but forces the use of a wiki to play the game to any degree of success. There's some fun to be had fumbling around, but you don't really get better understanding of how the world works after you get the basics.
That said there's a lot to do, from setting up farmland, walls and structures to help you survive the night. Crafting walls to help you survive against later attacks, all while needing to venture out into the world and get more materials or explore to find valuable materials to bring back to your base camp. It's also risky, do you set up a temporary camp to keep yourself out at night or do you spend a good deal of time travelling back to a place relative safety.
Game also has a great art style to it. If you're willing to sink a good number of hours into the game then you'll probably get a lot out of it. But prepare to die early and often in the beginnings of the game, failing to meet the game's objective of don't starve is the least of your problems in that world.
