I really like the new Knuckles intro, and how it connects to the main layout. Very nice. I have one minor criticism, and that's the placement of the rock/spring/rings at the end; it really should be moved right just a little bit as it currently looks a little off. (This is just like my criticism of Tails' new path in Launch Base Zone, whereby the layout didn't look right, and needed some refinement). The music didn't play for me the first time I started this version. Not too sure why. Closing and restarting it all seemed to fix it. I'm really enjoying the changes to the bubble shield to feel more like Mania. Feels a lot better to use now. This keeps impressing me with each new release. Keep up the good work.
