I got a problem, as my title for this thread says. When i enter the castle i can see the shining light falling down on a star. I know i have to look into the light in order to push the red button, which makes me capable of using red boxes later in game... But i can't. I simply can't get into the camera mode where i see through Mario's eyes... pls help me.. I have tried all keys on my keyboard (i play on a modded version on pc) and it doesn't work.
