Story: sonic,tails, and knuckles story is happeneing at the same time and tails was sent by knuckles to get the emeralds then give them to knuckles then to sonic so sadly no specail stages for sonic HOWEVER HE WILL BE ABLE TO GO SUPER (yes the other characters have stories of course I just chosed sonic tails and knuckles for this) Multiplayer: will have soem sort of race and battle and boss mode. Boss mode you can be the player and player 2 as boss or the other way around race mode not sure how I'm gonna do it but I dont plan on doing the race mode from sonic ultra battle mode just hit each other like the jump or something. Levels: so the levels are ok but they need to be worked out so right now there kind of short :( but the game is still being worked on though also I haven't added robots yet because I'm struggling to get them in a certain spot on the scroller
I hope this gives a better understanding
