Your friends can join in at any time and help you out building machines and go dungeon crawling together.
Starground is a top-down automation and roguelite combo. All progression trees are completey independent from each other, so you can play through in a truly flexible way. Spend all your time automating, dungeoning, or maybe a bit of both. There's no right way to play the game, and any path you take will let you win. If you want to play together, invite your friends to work on the same things, or divide and conquer each part of the game.
