@ anyone who's having trouble killing a horror, simply run close to the edge of the screen so when the horror launches it flying teeth, you can swoop in and splat it while its teeth are flying off screen.
See the turtle of enormous girth!
On his shell he holds the earth!
His thought is slow but always kind;
He holds us all within his mind.
On his back all vows are made.
He sees the truth but mayn't aid.
He loves the land and loves the sea
And even loves a child like me.
--Stephen King, Dark Tower III
