SWR Marisa's Theme: Vessel of Stars ~ Casket of Star

This is Marisa Kirisame's theme from Touhou 10.5: Scarlet Weather Rhapsody Why is it that "Magicannon - Final Spark" only fires diagonally in this game? It's strange, but quite fun to use against people who have never seen the spell before... Opponent: Ha, I jumped out of the way! Wait what-- ZUUUUUUUUN And Master Spark is also particularly toned down in this game compared to IaMP which had the magic circles and all that jazz, but still, Final Spark is so cool, except for the whole diagonal firing thing, which makes it kinda useless if you mess up the timing.
