Funny to see this just a few days after I’ve started building a Tron-like 3D game for the browser using Jolt[1]. So far Jolt is working pretty well but I’ll certainly be taking a look at this.
I'm a big fan of jolt because they have a more incremental way of snapshotting physics state which really reduces the amount of serialization and memory you have to do if you want to implement deterministic netcode.
