Actually, speaking of dancing mechanics, what if there was a way to switch between Auto-Dancing and Manual Dancing in-game? Like Auto-Dancing works similarly as it does in Half-Genie Hero, in that you can simply hold the dance button, then select an animal to transform into. Whereas when you use Manual Dancing, it works similarly to GBC Shantae's Dancing mechanic. While Auto-Dancing is used for the essential animal dances in-game, Manual Dancing is more used in puzzles and optional dances, either utility-based like healing/destroying or transforming into a secret creature (eg. a Tinkerbat), or the Auto-Dance works more like the Weapon Wheel in numerous games, where favorites are saved into the Weapon Wheel to use on-the-fly?
It could work in a diegetic way, where when a dance is used more often, Shantae can instantly tap into the magic more easily, though you could obviously move your personal favorites into the slots for easier access.
Honestly, that's the basis of how I've thought about the lore to explain the gameplay changes and "new game syndrome". First it was rhythmic dancing with lots of poses. Then just the final pose for each form. Then a single dance for any form. Shantae does (near) instant transformation now because she's been honing her genie magic and getting stronger. She "forgets" her other transformations each game because she's ~~so forgetful~~ trying to improve her magic ability, so she's limiting herself to improve on one dance form a time. When you gain the new dances in RR/HGH, she's gaining the inspiration to make the new technique work.
I might be in the great minority here, but I personally preferred the Transformation dances from the original game. It was basically their version of the ocarina songs from Ocarina of Time and Majora's Mask. I just loved that the ocarina was a tool you could use like you would in real life (I even used to look up how to play different songs on it like the Simpson's theme)
I can understand those who say it hurts the pacing of the game or whatever, but for me it made things more immersive. It felt like a ritual you needed to do to pull off something impressive. Like a wizard reciting a magical chant to perform a spell, or a DBZ character charging up before unleashing their attack.
They just made the game feel a bit more real because you actually had to do something to transform. And it made dancing part of Shantae's tool kit rather than the touch of character flavor that it is now.
Minority but not alone. I'll boot up my 3DS just to mess around with the dancing. Whether or not to warp around. God, I miss the ocarina songs add it is. I wish Skyward Sword did anything like that for the harpy so Fi had
a reason to sing all those random songs. I miss the dancing to. (Though I do think it needs the HGH world pausing so you don't get interrupted by enemies constantly)
I do think there should be both styles in some way. Like metroidvania platforming should be fusion style. The main animals and abilities. Like, I can see why the instant ability is important for that. I've played Hollow Knight recently and see how it can be incorporated well. But important plot or puzzle solving could require the old dance. Like needing to speak with a lingering ghost. Or a "detect magic" type of spell. The heal and obliterate etc should require the extra inputs though (and different routines for different strengths)
Four words: Water Temple Water Levels. If the magic of using the ocarina hasn't thoroughly extinguished for you by the time you finish that dungeon, you have the patience of a saint. And though the ocarina remains an important tool in the following game, it's use is nonetheless cut down quite a bit. Then the Wind Waker had to go and make it essential for the simple act of steering.
It is very much possible to have too much of a good thing.
The Water Temple requires you to do a full rotation twice to beat it. Changing the levels five times minimum. But that's all you have to do. Any extra rotations is you missing stuff on your own. It's really easy to get lost, but also easy to finish if you go everywhere you can while the water is at any particular level. Saint level patience helps significantly though.
Wind Waker shouldn't even be an argument because of where you can warp. Wind direction is only required in the very beginning. Afterwards you have access to free roam. Soon after you can get warping. Unless you need the very specific far bottom row and far eastern column of quadrants, you can reach everywhere fairly quickly you ever need by setting the wind to NW and never touch it again. And the command melody and prayer hymns worked well, certainly something Shantae could make use of, even a little.
