Precisely one problem
When you get your hat stack up to the Platinum level, it's impossible to dodge torches that come out on top of you or to catch hats that don't. That makes the last (and undoubtedly 100pt) medal completely based in luck, as anyone can get their stack to Platinum level but only the lucky few will have the torches and hats fall in the correct places after that. I have a solution though: any chance of giving us a split-second warning when a torch is going to show up? That would do nicely to solve this difficulty.
