I started a small side-project with websockets because I recently purchased a VPS that I can host the server on.
Multiplayer game development is something that I don't have much experience in, part from Chair Simulator which wasn't really real-time anyway.
Explosions, walking, colliding all work now with multiple people. Now I just have to make it into a game, with scores etc. Usually this is where I choke and give up.
I hope to release this soon, even without scoring. The interest in Chair Simulator motivated me to 'finish' it, and if the same thing happens with this project, then I may finish it too.
I'm still working on the level creation of the space game in the background. Some if it's in game already, but some only exists on paper.
