Then maybe you should not choose the same words in the same order as people who do mean it as an insult. It might help you avoid all this over explaining.
1. The Music? We have barely heard any tracks from it. Even well liked Yoshi games had tracks that people didn't like. Often those tracks were used in promotional material for Wooly World, but don't reflect the game. We can hope.
2. Just change the control settings. The options are in your control.
3. "All I'm clearly saying is the game isn't designed for adults first and foremost" and "it's clearly aimed at younguns" are not the only two options. Some of us are saying it's aimed neither at adults or very small children. But instead, both. Like some movies are aimed at men, some movies aimed at women, and some movies aimed at both. But just because it's not aimed at men does not mean it is aimed at women.
The reason early Pixar films are so beloved is that they were aimed at general audiences, but also were very appropriate for kids. The reason some Pixar movies have been seen as less good is that too many of them were in fact aimed at kids.
Ironically, I find those games (and many movies an TV showed rated for a mature audience) to literally be childish. To be aimed at childish impulses and gratification, which is precise why children should not play them. So here we have games aimed at 'mature audiences' that appeal to kids. Meanwhile, many games that people see as aimed as kids are not actually enjoyed by kids. It's fun!
You keep saying it's aimed at kids. The ultimate problem here is you are taking the final effect, and assuming it was both intentional and the correct interpretation of it. Maybe it wasn't aimed at kids, and they simply failed to make a good general audiences game like Mario Bros.
The title theme is painful and the simplistic main theme is getting used a lot going by other level footage. Especially the title theme, which is the first song you're supposed to hear, being like that doesn't fill me with optimism, even if I'm sure there will still be good tracks. You also can't change the controls beyond button mapping. You still can't aim and move at the same time, flutter jump is still infinite in normal mode, still can't spit out enemies, everything you can egg is highlighted removing any element of experimentation, there is no apparent flutter boost from jumping on enemies to heighten the skill ceiling. Yoshi still moves stiffly and the overall character control is still drastically reduced in complexity, which by itself both courts players who aren't as skilled, and limits any of the gameplay from being able to be designed to accomodate or even require thoughtful movement. It's Yoshi gameplay streamlined and simplified. It's not about jumping with the A button. These controls can't allow very complex platforming/enemy challenges, and the highlighting of everything you can hit with an egg means you can sweep the screen at any moment to see what you need to hit instead of figuring things out using logic.
I get what you're saying that just because it's not aimed at a hardcore market does not automatically make it aimed at kids. But from my impression of the game's overall elements, I have the perception that it is indeed for kids.
This feels like splitting hairs at this point. The game is obviously designed to be appealing looking and easy to pick up for kids, that doesn't prevent or exclude older players from the equation. Making a game for kids isn't the same as making a game that's anti-adults. People will play any game at any age and Nintendo is aware of this. It's also true that a lot of older kids hate cute aesthetics such as Yoshi's, but the younger ones will dig it. I agree that those other games are childish in nature, but that doesn't mean they're aimed at children, especially GTA. They're enjoyed by kids but not
for kids. I don't think it's a false statement to call a Yoshi game like this
for kids even if it can and will be enjoyed by adults. The actual aesthetic and callbacks to Yoshi's Story are clearly meant to appeal to adults who played Story when they were young, inviting them to relive an experience that was aimed at a younger audience than Yoshi's Island was. Personally, I think Yoshi's Story was more engaging in its first level and in its overall gameplay loop, but I'll remain hoping to be surprised by later levels.
