Four years ago today, I uploaded my very first Danmakufu video. Several scripts and one engine switch later, I thought I'd commemorate the anniversary with a little blast from the past!
I recommend using this Reimu player (http://www.bulletforge.org/u/mr-blue/p/reimu-hakurei/v/10), as the script was balanced around it. However, you should be fine with most other characters.
