Basically, there is the concept though. Tails and Knuckles have been captured (O NOES), and Sonic is out to save them. Along the way he can use Knuckles and Tails powers by hitting a monitor or power up post. From a design point, this makes level design a hell of a lot easier for me, only having to think of one character. Oh, there are also a crap ton of new shields too.

Special stage concept. SCD and blue balls combo.
And a video to get the idea across.
See how dem power ups work?
The shields are refreshing too. And as always, robotnik as a boss.
So, my main question is, is it worth finishing?
