One of the first buildings you’ll come across is a Field Station. It’s used to analyze items in your inventory to unlock the crafting recipes they’re used in. You can only analyze three items to start, though, with charges then building up over time, so choose wisely.
To start, you should analyze a Pebblet, Plant Fiber, and Sap. That’ll unlock the Pebblet Axe needed to get very important materials, the Workbench for more advanced stuff, and the Woven Fibre, again, needed to make the axe. After that, you’ll probably want to research the Sprig next. Anything after that is up to you as you explore the grassy reaches of the garden. Just don’t take too long between trips. There’s nothing worse than having an inventory of items to analyze and only three charges left to use.
