About the game
Players can jump into hundreds of community-made games across genres such as shooters, roleplay, racing, and platformers without installing them. Friends can join together through multiplayer, without setting up servers.
Creators use a modern editor with C# scripting and real-time hotloading to build games, publish them to the platform, and earn money through a Play Fund. Games can also be published to Steam as standalone titles.
