It just so happens that I finally got PCB to run at a normal speed in fullscreen today. Normally, fullscreen would send it up to 720 FPS. All I did was check off the DirectX box in the config file.
It's a real joy to play that game, especially using Reimu B, and it's even better when I can see what I'm doing during those bullet-heavy moments.
While Mountain of Faith was the first game I played - because it was the newest - the name "Perfect Cherry Blossom" made me chuckle initially. I thought it was going to be fairly easy with that pretty, floral name. And it wasn't too bad until I hit Stage 4 and was attacked by ... a fairy. Lily White tore me up one side and down the other. I learned an important lesson about respect for fairies that day.
So don't laugh at fairies. They will open for you a world of pain.
