In a tweet that went up a few hours ago, Headcannon confirmed that they have contributed to the upcoming new content for Sonic Origins Plus, including Amy Rose’s new sprites and Knuckles’ campaign in Sonic CD.
Headcannon specifically calls out the work of team members Andy A-Start and DashPadSPD for design and data management in the expansion. In addition to the character updates, Headcannon also supplied additional enhancements which were not specified. Closing out the thread, the team thanks SEGA for their openness to the developer’s feedback and suggestions, and they appreciate the level of trust SEGA put in them.
Headcannon was responsible for bringing Sonic 3 & Knuckles to the Retro Engine in Sonic Origins’ initial digital release. While our staff has had very positive experiences with collection, some members of the community and members of Headcannon itself have expressed dissatisfaction with its technical shortcomings.
