Man I don't think I'm gonna use coins on continuing special stages anymore, don't particularly enjoy the bonus games and don't really care about super emerald stuff (according to le FAQ https://gamefaqs.gamespot.com/pc/620568-sonic-3-and-knuckles/faqs/18497 , these get you super overpowered forms of the characters : P), would rather use coins to unlock the cool calendar art in the collection's Museum!
Flying Battery Zone is my least favorite so far. Still got half to go! : P Launch Base was pretty epic though, and Mushroom Hill is wild! ^ _^ Espio's stage in Sonic the Fighters is based on it! ; D https://youtu.be/y2r3sL9pvko?t=1335
