im coming back to the game in order to 100% it, so far ive beaten all C sides, got the moon berry and planning to get all the berries for the moment, ill look into golden ones after this hell of a level, i dont know how to perform this (corner kick i think ?) and ive been at it for more than an hour so im done trying random stuff to make it work, please explain it fairly easily.
