Spicy Horse's latest crowd-funded effort will need another source of funding beyond its Kickstarter, which will only deliver "some initial chapters".
"That amount is less than what we'll need to develop the full game, but enough to get us started and deliver some initial chapters," the developer said.
"We'll need to throw some of our own funding at it, work to secure outside funding (perhaps via publishing deals) and find other creative ways to bridge the gap."
Other sources of funding Spicy Horse could conceivably draw on include venture capitalists and sales of other titles.
As McGee pointed out, many studios draw on multiple sources of funding in order to complete projects - as Double Fine is doing with Broken Age, which it will release in two halves in order to deliver the indie's full vision.
"This is the kind of thing we do constantly as an independent studio, so I'm confident we can use whatever funding we secure to make an excellent product and expand on whatever gets built first," McGee said.
