Hi pedropss, my child has 5 months, wife need my help when I'm at home, etc, so, it's pretty hard to make anything else than helping she.
When in vacations, I do expeditions, travelling to the Pantanal, Argentina, Uruguay, etc, and that's another world where I'm learning too.
Maybe in 2015, when the Construct 2 get a mature state of this multiplayer online support, and improve some other things (thing in the to do list and know by Us), I'll give it a try.
You're doing well, I have spend around 2.000 hours with construct 2, plus 4.000 hours doing pixelarts for various purposes.
Also, the best way to learn is helping people in the forum, so, take little challenges and keep learning and improving your knowledge. Also, ask for help and read old posts from the Scirra Gurus, because they are amazing persons always ready to help.
