Developing a 3D Puzzle Game Guillaume is a star developer. Professional, super skilled, mature, excellent communicator. It was super enjoyable working with him and there was no task or feature he couldn’t handle. If I ever build a game studio with remote developers he will be the first I’ll try to hire.
