I've read google hangouts API developers.google.com/+/hangouts/api
To create Hangouts Apps,
The API is in Javascript, so I thought to myself, why wouldn't I making a plugin for construct2 to make games for hangouts.
The API allows you to make multiplayer games over the hangouts framework without the need of a Socket.IO/Node.js server, and I think it'd be a great addition for hangouts (:
Would you be interested in such a plugin?
If so... stay tuned
