Hey i have a problem with Mario Galaxy 2... When you shake the remote Mario spins, but it normally breaks crystals and stuns enemies but it doesnt do that so
Tldr Mario's Spin attack doesnt break crystals
You need to break a crystal at the 3rd star so i cant progress
Are you talking about in the 3rd little planet in the intro section where you have to break the big crystal to fall down the hole? Or somewhere else?
Things to check:
1. Are you making sure you're close enough to the crystal?
2. Have you been able to break other crystals before?
3. Are you using a real Wiimote, a controller, or mouse/keyboard?
4. If using a controller or mouse/keyboard, do you have shake X/Y/Z hooked up to the same button so that all axis would get a shake when you press the button, or just 1 axis? Usually shaking all 3 axis is required...
