What are you playing?

[NICKtendo DS]

After hours of practice in Time Trail, I managed to beat the game with a Good Ending.
While I feel awesome for achieving this, I still can't justify the lack of control in these Special Stages. S3&K may have Special Stages where you auto-run aswell, but there the Blue Spheres don't fly all over the place, plus the grid helps. CD's Special Stages are still the worst along with Sonic 2's IMO.
I have 3 achievements to go. My next run I'll destroy all Metal Sonic holos and Badnik Generators, I have to collect 200 rings and I have to beat Metal Sonic without getting damage. The first I did with Tails, but that doesn't count apparently , so I guess I'll manage with Sonic. 200 rings is going to be tricky and beating Metal Sonic unharmed is going to be absolute hell.

EDIT: Got the 200 ring achievement.
