Don't know if anyone uses this, but I created a Node.js server running socket.io with Nodejitsu.
I was able to get the server running but wasn't able to connect with either the Construct2 WebSocket plugin nor Zack0Wack0's socket.io plugin.
Can't say I'm good with servers, but I was able to create a multiplayer pong game with a local Node.js server.
I must be doing something wrong, just not sure what.
Any suggestions?
