I won't repeat the changes I already mentioned on the previous post, so here's the Progress so far..

• Completely reworked the following Stages:

  Sonic's Angel Island
  Sonic's Cursed Cave
  Tails' Angel Island
  Tails' Cursed Cave

• Added a new "Special Coin" monitors

  What the coins do is that they provide extra retries for the special stages, In the "Normal" sections of the special stage, if you fail a round, you get to retry that round again, not the whole stage from the beginning.
  
  It doesn't immediately kick you out like it previously did.
  But it does not provide any extra help with the "Non-Normal" section.
  
  These coins can be found in monitors scattered around the zones, but It was only implemented with Tail's Special Stage so far.
  
  (idea was recommended by @PicoDigitalStudios )

• Slight, and probably unnoticeable, modification of the "My Head It Hurts" Zone
