lol... at this one point, I died because I was climbing above a pit, and I had to jump and glide somewhere, but since I had over 50 rings it made me turn into Super Knuckles instead, and I couldn't glide because of that and died in the pit...
I really hate those explosive enemies in Metallic Madness that spit out smaller versions of themselves.
Seems Knuckles doesn't get to fight the true end boss when you beat it with all the emeralds.
No way! Blue Spheres is now unlocked!
After that 2nd playthrough, I now have all the blue spheres levels beaten, and 8/32 of the gold medals on them.
The unlocked Blue Spheres mode includes the original Blue Spheres stages from Sonic 3, as well as completely new Blue Spheres stages in "Mania" mode that weren't in the main game... like with some green spheres that turn blue after you hit them once.
