I finished up Girl Meets Boy, a 2 player co operative platforming game playable on http://www.synaptop.com.
Girl meets boy uses both Construct 2's multiplayer plugin and Synaptop's API for networking the 2 players and can be played on any device for free.
Here's a screenshot of the game:
As always, feedback is welcome and encouraged.
Edit: now I have an external store page for the app: http://www.synaptop.com/synappstore/app ... /ID-254556
