Who knows what now ?
The animation was decent yet lacking any actual closure. All we got from that was "Oijoink Knows" something about someone.
Perhaps continue the animation with a sequel or extend it so that it will explain in greater detail what's going on.
Finally, don't assume people won't replay. For the sake of reviewing it I would've actually used it.
PS: If all you wanted was to say "Only Oijoink Knows" without going into detail and without explaining the context properly I really hope this gets blammed.
