The sounds make the experience. I need good fart sounds.
I found them here, by michorvath
"A series of flavorful farts." -- who could beat that?
What I like is that there's variety and they're all with the same quality and sound/noise profile.
And flavorful. Let that word swish around in your mouth. Or don't.
Hearing the variety while working on "hovering" made me come up with the idea that no every fart should have the same "thrust" power.
And thus the game evolves!
