Gzowo Builders

A creative sandbox with real physics: you place parts on a quarter-metre grid, wire pistons and hinges to buttons and timers, and drive whatever you came up with. There is no survival mode and there never will be — the whole game is the workshop.

The interesting part is what holds a build together. Every construction is one rigid body, and the joints between parts are a graph; when a bridge in that graph carries more force than it can hold, that piece tears off on its own. Nothing is scripted — an overloaded cantilever fails because it is overloaded.

Wheels are raycast rather than physical bodies, which is why a car at 40 km/h through a slalom keeps all four corners instead of shaking itself apart. It runs co-op over the local network, with one machine acting as the authority on physics and running exactly the same code the browser runs.
