"We built up systems and then we removed them to find better systems."
I believe that game jamming is the best hobby in the world! I run game jams, research game jams, participate to game jams. In a jam team, I usually take the role of a graphic designer, but sometimes I've been a gameplay designer, junior "coder" (ah, Construct 2 might not count), and even a seamster (we made phygital plush toy!).
I also run a non-profit organization Finnish Game Jam, volunteer for Global Game Jam and help everyone interested in running game jams. Jam jam jam!
