This past week-end I participated in my first Global Game Jam, and it was a blast. It was in the center of Paris, in the Isart Digital school, and the idea was to make a game in one week-end. We were 4 guys and we worked about 35 hours to make "The Loop" (PLAY).
The goal of the game is to surround enemies, and destroy 'boss structures' by flying into blue links. It's inspired from Flow, Geometry Wars, and other top down shooter. Except in our game, we don't shoot :)
