Hey guys,
Thought it might help some of you.
In the last 2 days I tried to implement Multiplayer in construct 3 with the most simple way I could find.
After researching, I found out about Photon which is a MMO playform that makes life easier for game devs.
Here is the usage example

The Project file is also attached to the example
Have fun!
