In the game description we put the crafting recipes Since you can only have 9 items at a time , your items will change when you try to collect more so keep an eye on the symbols at the top right. You also need at least 1 food and 1 water in your inventory before the day is over (the icons look like a ham/chicken leg and a water drop)
We'll add a crafting book and item log in game at a later update :)
