    Touhou sprites (OFFICIAL)

All sprites belong to 黄昏フロンティア (Tasogare Frontier/Twilight Frontier) and were ripped and published to The Spriters Resource. DISCLAIMER: I only borrow Twilight Frontier assets used in official Touhou Project games, which are limited to:

    ⁃ Immaterial and Missing Power, Scarlet Weather Rhapsody, Touhou Hisoutensoku ("retro Touhou fighters")
    ⁃ Hopeless Masquerade, Urban Legend in Limbo, Antinomy of Common Flowers ("modern Touhou fighters")
    ⁃ Sunken Fossil World
This means I do not use artwork from games such as Super Marisa Land.
