Overview:

Soko'Banshee is a puzzle game involving a banshee in charge of pushing souls back to their gravestones. The main character plays a human that picks up a banshee's silver comb, converting her. The only way back is to finish the game, or become a crying banshee forever.

History:
This game was created in 2000, a cleaver remake of the generic "sokoban" clones, and re-clones. The same engine for "shrooms" was hacked to make this game possible.
