Ok, fully completing the game is optional, and it's not supposed to be easy, so don't complain about it.

Anyway, to see the end video, just play Proud Mode. Then you only have to lock all the keyholes, you don't have to complete the minigames.

Of course, I got 100% on Journal and Gummi battles in Proud Mode anyway, but...

Anyway, you don't need High Jump 3. Aerial Dodge 3 is much more important. In a 30 seconds or less run, you shouldn't touch the ground at all once you make your first jump, making High Jump useless.
