Touhou Shinjutou: Hollow Song of Birds

One day, time is stopped in Gensokyo. Sakuya Izayoi, being unaffected by this as a result of her abilities, travels to the Hakurei Shrine to free the two main incident solvers, Reimu Hakurei and Marisa Kirisame, from their eternal time prison. These three then set out to find the culprit behind this incident.

Touhou Project fangame developed by raichu, ido, and Shijimi Nono with music by Wanwan. The game centers around a time-stopping incident in Gensokyo and features a gem system providing 7 different optional powers.
