I really enjoyed it and I admittedly played it more than Super Mario Bros Wonder, but I enjoyed both nonetheless.
A few things though they should do in the next 2D Sonic though, ditch the Genesis style music, something Mania achieved, work on the multiplayer so that it’s not as bad as it is here, bring back the emblems from the Sonic Adventure games, make them mandatory for accessing new zones, and have players earn them via the mission structure of Sonic Frontiers.
