This is the B route on Lunatic difficulty in Boss Replay mode (fast forwards throughs the normal enemies) which takes you against Marisa Kirisame. (The game has two different stage 4 bosses, and if you use Marisa's team, then you fight against Reimu, one of the characters in the team I'm using)
This was just a practice to unlock Marisa's Last Spell. Not that good of a run, but it shows what playing Touhou games (and danmaku in general) is like.
Will likely be replaced as I improve the replay.
