and the 25th coin??!

So how does the game end? Am I supposed to find all the coins? I have 24 coins and nowhere else to go.

By the way I have the pre-release version.

You have many places to go still!

I have found that secret ability at the warp zone, but I don't even know if I am supposed to find all the coins to end the game. Is that the goal?

I think there are a few goals in the game. First/easy/normal game ending is

Another is to find all the coins.

Have you found the place where you need the new ability?

No I haven't, I'll try later. But the lack of any kind of guidance, story or goal was rather disorienting from the start. I assume that this has been adressed in the final version of the game and that there is a story/goal?

Also, no. the game doesn't have a plot or real goal. the goal its to just have fun  .

What level is that hidden door?
