Once you get all 100 treasures, you unlock Time Attack mode. The goal is to get all four keys, then leave through any exit door. I'm probably not going to be doing every level for this, and, if so, I'll be doing them off-screen. But, I figured I'd at least demonstrate one level. Now, if I decide to do the rest of the Note Coins, I'll try to record those, but...I don't think this is going to happen. Not after the result I got from playing the Golf mini-game one last time...
