Once upon a time, in a swampland dreary, a fly awakened, weak and weary. Possessed of hunger, it set out on a search to find a morsel, a corpse, to stop starvation. But there was no death to be found in the swamp, only tormented life. It journeyed on, meeting strange creatures living in the swamp, ever sadder and more tortured, until, by chance, it happened on something delicious.
PLAY AS A DIRTY FLY
You are the fly. Play as the dirty, filthy, corpse-eating fly on a mission to devour a monster living in a bath in a house far away.
A GROTESQUE TALE OF HUNGER & SURREAL HORROR
Meet grotesque, surreal inhabitants who will ask you to do surreal and horrible things. Do them and eat horrific things to sate the fly's hunger for dead flesh. Then restart the tale and choose a different path through the story, eating your way to three different endings.
Be the fly. Explore. Meet depressing caterpillars. Experience a disturbing tale of existential horror. Welcome to the next brainchild of the creators of The Repairing Mantis.
