I was such a big fan of Don't Starve when it first came out on PC. I was convinced that I would be able to survive and create a beautiful world that I could live in! For those who have not played Don't Starve, it's a survival game about spawning into a very hostile land, full of monsters, where you need to try to survive. One of the main things that will kill you is your sanity and the lack of food. You'll need to start gathering items, crafting things to help you survive, and avoiding (or fighting!) monsters that appear. Don't Starve Together allows you to play with others, so that you all have a better chance of being alive.
In Don't Starve Together, you can set up your own server easily, picking some of the different options like how challenging the difficulty is, whether there are caves, etc. You can then select your character. There are a bunch of different characters with different stats for their health, hunger and sanity. Some even start with specific items that can make things a bit easier on you, depending on how you play.
You then end up in the procedurally generated map, which does have a day and night cycle, in the summertime. Your goal is to start making moves to keep yourself alive. There are plenty of strange monsters, from giant eye-monsters to dark figures that only appear when your sanity is too low. You'll be followed by monsters during the day and night.
I spend a lot of my time in Don't Starve collecting items. I am not very good at fighting, so I look around for a pig village or a herd of beefalo, so that I can then use them to keep myself safe by using them to fight off any monsters that I need. You can craft this bell that bonds you with a beefalo, which is one of my favourite things to do.
I then start crafting! Once you have a science machine up, you can start crafting items in Don't Starve Together that can make things easier - gardening objects so that you can create a farm for food, the ability to set traps in bunny biomes, and a sleeping bag so you can get back some of your sanity. There's a big focus on managing your inventory, your chests, and yourself as you explore around and try to make it back to your base before it's far too dark.
Don't Starve Together works fine on mobile - the placement of the UI is very good, and I do like that to craft something, if there are individual items that need crafting before the main item, you can just tap on the individual items in the main item area and then craft the main item. It's just very well designed, which is ideal when it comes to such a challenging adventure. I will say that I did play this before it was public (so there wasn't a good choice of servers), but there was some buffering that often happened alongside the movements that I took, which did hurt the gameplay.
