Sonic's 18th Birthday ^_^

[Vipershark]

here's what they need to do
either go back to a 2d or 2.5D sonic
or make a 3d somnic like sonic adventure
sonic, knuckles, tails (and possibly shadow for speed teamups) playable
no other playable sonic friends
running
fast running
but with platforming
that is fun
it can be like the original 2d games but in 3d
each character has their own path, but if you're skilled enough you can get into another
sonic can take the low, speedy route
tails can take the high, flying over stuff route
knuckles can take the middle route which involves running as well as wall climbiing and glindg at stuff
but all 3 routes can still be completed by all 3 characters, and paths can switch
