My name is Bill Hansen, I have been working with Sonic Team and SEGA Technical Institute until I quit around July or June 1998. I have contributed to most of the 2D Games such as Sonic the Hedgehog, Sonic 2 and Sonic Chaos. I have also slightly contributed to the development to the Megadrive. Thank you for reading. I have a Twitter social media account. The username is named "sonicarchives1" (Also just to clarify, this is all fake.)
