Yeah... and we can use Dropbox - Project Sharing. Idk if it works with construct 2, but it does with java + Netbeans. Modify the code, then it's updated on dropbox and on each computer sharing the code file.
I will start to do something right now, with some paint stuff made by me.
People may get motivated to collab if I show something
