The Sonic the Hedgehog project began with just Naka and Ohshima, but grew to involve two programmers, two sound engineers, and three designers. Hirokazu Yasuhara joined to supervise Naka and Ohshima and develop levels, and became the lead designer. He satisfied Naka's request for a simple, one-button design by having Sonic do damage by jumping. Sonic the Hedgehog was released in 1991 and proved a major success, contributing to millions of sales of the Genesis. The team took the name Sonic Team for the game's release. Naka referred to Sonic Team as only a "team name" at this point.
