Antinomy of Common Flowers

Touhou Hyouibana ~ The Antinomy of Common Flowers (東方憑依華 ～ Antinomy of Common Flowers.), often abbreviated to AoCF, is a fighting video game developed by Twilight Frontier and published by Team Shanghai Alice for Microsoft Windows in 2017. It is the latest fighting game in the Touhou Project series, being a continuation of the extra story mode from Urban Legend in Limbo's PlayStation 4 port, released in 2016.

Antinomy of Common Flowers ports for the PlayStation 4 and Nintendo Switch port were announced in May 2019, and released on April 22, 2021.

Gameplay
Antinomy of Common Flowers is a fighting game in which the player will attempt to deplete their opponent's health bar using various moves, such as basic punches and kicks, as well as more complex special moves, which require special inputs in order to be performed. Spell cards, special moves that are considerably more powerful than the regular special moves, can also be used by charging a meter through damaging the opponent, which once full, allows the spell card to be activated. Each character in the game has a total of three spell cards to choose from. Antinomy of Common Flowers has no ground, allowing for complex aerial movement.

In Antinomy of Common Flowers, the player will control two characters in any given match. The 'master' is the main character that they control, and can temporarily switch to their 'slave', who can be used to quickly extend combos. Additionally, when the player takes damage, some of their health will be retained with a white bar, and when playing as a slave, the white health will slowly increase. Taking damage while playing as the slave character will decrease the player's 'occult meter', and if it is emptied, the player will be forced to switch back to the master, until the meter increases again, which will gradually happen by default, but it can be increased faster by damaging their opponent.

In Antinomy of Common Flowers, the player can engage in single matches, either against the AI or with other players online, play a training mode in which they can freely test their attacks, or in the game's story mode, wherein the player will fight many enemies in succession, and can unlock new characters by defeating them.

Plot
As part of the Urban Legend Incident, a phenomenon called "Perfect Possession" occurs, in which people have their mind and body completely taken over by somebody else. Reimu sets out to investigate the cause of the Perfect Possession.

However, they complained that a lack of players made it difficult to find matches with other people online. Comparatively, Noisy Pixel rated the PlayStation 4 version 7/10, praising its soundtrack, art direction, and gameplay, but lamented the lack of a move list on the game's pause menu, as well as the "somewhat spotty" translation. Movies Games and Tech gave particular attention to the large number of characters and gameplay options, but criticised the game's input lag and lack of voice acting.
