With this plugin you can enhance your game with local multiplayer (bring back the good old times, where people play next to each other
Players use their smartphones to connect to your game and control it.
Plugin Documentation: developers.airconsole.com
We are also having a HTML5 game contest
starting soon - so if you are interested let me know or check our twitter account 'AirConsole' for updates.
Hope you enjoy it!
We are looking forward to see some multiplayer games made with Construct2!
