If a new Touhou fighting game were to be made, what would you like it to play like? What characters would you want? How would they play? This topic is just for the sake of discussing ideas for Touhou fighting games, official or not.
Starting off, I feel like Yuuma would work since she could use her giant spoon as a weapon. I think having her play similarly to Android 21 in DBFZ would make sense. Maybe give her a command grab where she bites into the opponent and gains attributes based off the temperament of the character (for example, using it on Marisa or Joon would cause Yuuma to build more meter due to greed, Cirno or Tenshi would give her a defence boost due to their confidence, etc.) Assuming the fighting game plays like Soku, that could be Yuuma's 623x. Her 236x could be sending out Eagle spirits, with the B version being a regular one while the C version is the stronger ones from 19. They could be used as a way of overpowering danmaku since they could take several hits. You could give Yuuma a 421x where she pulls a rock from the ground as a strong projectile, which she can then send at the opponent by hitting with her spoon. While 214x can be a geyser, which can control the vertical airspace. Maybe give it an air version too where it can act as a divekick, since she does something similar in her 17.5 boss fight.
