PCM - Grand Prix

Let me enjoy my glorious moment before I fall into the bottom again, haha.

I don't really know how the ranking system works, but it seems they will categorise 50 players to compete with each other. I was in rank 11 last grand prix with the first rank scored 500+ stars. That's really a big ambition there. Master Café mode is hard at first, but when you replay it again and again for 2 times or more, it's actually not that hard. Luck play a big role here as well. I really hate Munchlax icon (I don't hate the pokémon, in fact Munchlax is one of my favourite pokémon) because it's kinda hard to move. Sometimes, It will stuck and then I fail my order. Is it only me that experienced this?
