IMO sandbox games are games in which players have the freedom to do things that make gameplay non-linear, such as exploring the world or building structures. Sandbox games can also be based entirely on player creativity, like creating levels or even entire game modes (or games) within a game

Lemmy is the backend (server-side code) and lemmy-ui is the frontend (client-side code that runs in your browser). The first one is used for installation, the repository has links to instructions

Hi, I can access it now too, but I couldn’t before. It’s weird.

Thanks for the reply, but that’s not what I meant. I understand that the Jerboa community is on a different instance. What I meant was that, for example, I can subscribe to memes@lemmy.ml, to fediverse@lemmy.ml, but I can’t subscribe to jerboa@lemmy.ml. And I can’t even find it through a search (on jeremmy.ml). Seems like a federation problem, or it’s a feature I don’t know about.
