Perfect Cherry Blossom (InstanceTopic, 17)
From Compile Worlds
Perfect Cherry Blossom is the second game in the Windows Touhou series (making it the seventh overall). But since Touhou is not a series (All the while having the word "series" on its title), it's not a real sequel to Embodiment of Scarlet Devil. In this game, Reimu (Or Marisa. Or maybe even Sakuya!) goes on an epic adventure to get Gensokyo's Spring back from scary ghosts. And to plunder cat homes of their treasure. Jerk.
This game is like the last one, except that it has ghosts and Spring, and that alone already makes it awesome, among other things (Not as awesome as its "prequel", though). One flaw is that it nerfs the death margins to impossible lengths (Well, only Reimu, anyway) so it's not as challenging a game as its "prequel". Just... watch how you go with Stage 4 and the Prismrivers!
