, and Sonic Adventure
After leaving Sonic Team, he formed an independent game company called Artoon, of which he is currently president. There he went on to work on such games as Pinobee and Blinx: The Time Sweeper, and in 2004, the sequel to Blinx, Blinx 2: Masters of Time & Space.
He is occasionally credited under the nickname "Big Island", which is a literal translation of his family name.
