Well, I kinda sorta beat the game like a day after I posted this. That was kind of short. I wasn't expecting to meet the end of the game so soon (as soon as I got 70 shines - I have 84 now), I hope it's only just a mid-game-boss that I beat or something like Super Mario 64 (where after 50 stars you beat the 2nd bowser) because that was too friggin easy.
