My biggest problem with Sonic Frontiers is the Cyber Space stages and Sonic's control in those stages. I don't know about anyone else, but when I played the stages that replicated the ones from Generations it just felt different and not in a good way. Sonic felt stiff and really unreliable to control, a stark contrast to the open areas. Sonic controlled a lot better in Unleashed, Colors, and Generations. It felt like they took the controls from forces and used that for the cyber stages.
