watch until the end (or better yet, skip to 21:23)
Mountain of Faith is a game, looking back on it, is very well-made, but at the time, I couldn't help but feel I was playing with a slippery Reimu, dying to patterns I shouldn't have. I felt a little more inclined to trying to cheese this game after having been so trolled by it... and after a few tries, this is the result.
Reaching the final boss, the final spellcard, "Mountain of Faith," I start freaking out and bombing whenever I see a row of cards about to hit me, getting off-tempo for the pattern. I end up at the base power at my last life. I manage to calm down and focus a little, getting into the rhythm of dodging and shooting. After what feels like an eternity, I suddenly begin to hear that dull sound that occurs when the boss has very few life left in the card. And I think, oh man, wait, am I actually going to clear this? I keep shooting and dodging. The game slows down. Oh man, she's dying, YES!
And suddenly
we both went pichuun
I died during the last possible seconds to die
The following attempt was a 1CC; but crashed shortly afterwards. This is the closest footage I have to an initial 1CC of Mountain of Faith, and somehow, I wouldn't want it any other way.
