Resonite Everything is editable

There is no line between the game and the tools. The home world, the default avatars, the video players and the color picker were all built with the same tools you get, so you can take any of them apart to see how they work or build your own version from scratch. You grab an object, rescale it, recolor it, wire it up, and save it to your inventory with one click to spawn again in any world. Made something you like? Favorite it, copy it, hand it to a friend. Even your avatar is fair game: shrink someone's limbs, change their materials, pick them up and carry them around. It is less a game with a sandbox mode than a place where the sandbox is the whole thing.

Collaboration here is the quiet kind: you and other people edit the same world at the same time, and everything just stays synchronized. No exporting, no merging, no waiting for someone to finish. The engine handles it, so a friend's changes appear as they make them, whether they are across the room or across the planet. You can start with brushes and simple procedural meshes and work up to tools closer to real game development software, except you are using them in VR, standing next to someone, both of you reaching into the same scene. When you are done, one button saves the whole thing, and shared assets are stored once no matter how many copies exist.

ProtoFlux is the visual programming language at the heart of the creative tools, and it is powerful enough to run everything from a door that opens when you boop it to full games and systems. You wire logic together as nodes, and it responds immediately: no build step, no waiting, just change something and watch the result. It can reach anything in the world, your items, your avatar, or all three at once, and it handles waiting and timing as a native feature, so multiple async flows can run off the same code. There is even built-in websocket support for talking to outside applications, custom hardware or your own game servers. If you have ever wanted to learn programming by building things that talk back, this is a gentle and very deep place to start.

For hanging out with friends, the appeal is that a session is whatever you make of it. Drag and drop pictures, music or videos into the world and everyone watches together in sync. Stream your system audio in stereo and play DJ. Change your avatar's size mid-conversation, switch to flying or zero-g, or walk across a Möbius strip if someone builds one. Sessions can be public or fully private, with an access list you control, and you can be present in several worlds at once and hop between them like browser tabs. Voice is low latency, text chat handles invites and voice messages, and you can send an actual item to a contact instead of describing it.
