The player controls Reimu Hakurei or Marisa Kirisame through 5 stages where each stage involves fighting a Touhou Character in a vertical shootout style game. This game has no plot or story as it is an arcade game.
The player starts out with 3 lives and 1 bomb. Points are gained via the number of hits done on the boss, the number of graze points and the number of lives left after the encounter. The scores will also show the number of clears on a stage (ie. defeating the boss).
Reimu has a lower damage rate in comparison to Marisa, however two of her missiles will home in on the boss regardless of where Reimu is positioned.
- Spirit Sign: Fantasy Seal
Reimu's bomb involves firing large multicolored orbs that home in on the boss dealing massive damage. Enemy bullets within the path of the orbs will be erased.
Marisa has a higher damage rate compared to Reimu, however her bullets do not home onto the boss making her only useful if she's constantly positioned in front of the boss.
- Magic Sign: Stardust Reverie
Marisas bomb fires an array of stars around her that spreads out across the field effectively wiping every single enemy bullet around her. Doesn't deal much damage on the boss however (in comparison to Reimu's Fantasy Seal)
