I'm gonna be honest, the flies don't really have any lore significance, at least they weren't created with the lore in mind (I guess they could be seen as foreshadowing that the man is going to die soon). Mostly, I just wanted a mini-game that could break up the somewhat basic mechanic of "wiggle the man's body parts," and flies that moved around the screen was the best idea I could think of. Thanks for playing, tho! Glad you enjoyed it
