We had a very busy weekend a week ago - during Gamedev.js Weekend we've organized a workshop and a hackathon, both about HTML5 games, and I think it went very good.
It's not that Gamedev.js workshop #1 was my debut in a role of the workshop lead - I did run one at Mozilla Festival in 2013 and the other at BrazilJS in 2015 - but it was the first one in Poland and at the same time the first one ever organized by me. I wanted to do it for the past few years already, but it's better late than never.
