Completed Perfect Cherry Blossom on normal.
Now, I know what you're thinking. Any half-baked bullet hell fan can do that. But there's more to my story than that.
Technically, this isn't my first time beating that. A couple years back, when I first discovered Touhou, I started with perfect cherry blossom. I was sucked in: I loved it, and kept coming back for more even after trying the other games in the series. After dozens upon dozens of tries, I finally, finally beat it on normal. Shortly afterwards, my interest waned, and I began to move on to other things.
Then, as it does, my interest returned. Several months later, I came back, and began right where I left off: PCB Normal. And yet, my skills had deteriorated in that time: I couldn't quite manage to beat the game again. Eventually I gave up, my interest waning again. This repeated for quite a while, until a few days ago. That was when I finally, after numerous tries, managed to recover my claim to fame: A 1CC clear of Perfect Cherry Blossom. I was finally once again as good at Touhou as I ever was.
The kicker? I won with two lives and two bombs left. After all those failures, I finally claimed victory with room to spare.
