They are a cool concept. They were excecuted poorly.

They should have been a power-up. Something that you can obtain to get to better areas and get mroe rewards.

They should not be mandatory for completing the level. This is telling us that Sonic can no longer complete even a simple level of his own power anymore and must rely on the Wisps.
