Pretty much.
Single button controls, except it causes annoyances instead of introducing innovative restrictions and limitations. It wasn't even really single button, you had a dedicated switch costume button.
Excessively ambiguous story telling. Far too much is left open to interpretation, it fails to strike that balance between giving the audience just enough to get a grasp on things, and withholding enough to maintain intrigue.
There's a separate novel that gives you the details, but they're apparently just the workings of an author interpreting the game instead of coming from the core dev team.
Scope creep, too many outfits are introduced for the sake of more stuff to do, but they often produce nothing of value and are duplicates of previous abilities. Box Fox is notorious for turning into a cube that does nothing and is prone to falling off edges when you lose all control.
Tedium, there's shit like Balan's Bouts which are repetitive QTE sections that you don't get a second chance at, until you defeat a boss. They aren't enjoyable the first time you do one, and they won't be after the twentieth.
Unnecessarily obscuring mechanics. There's shit like the chicks that follow you around and how you can feed them, but not much reason given why except that there's a breeding mini-game that if you somehow make the effort, you'll get access to the ultimate costume that gives you complete freedom to fly around.
The difficulty system where enemies gradually get more challenging the longer you go without taking damage, but resets to the easiest difficulty when you take a single hit. This adds into the tedium.
The project needed some serious wrangling to shape the bad ideas into good ones and not let things get out of hand.
Anything that could be said about Balan Wonderworld, has already been said at depth though.
