They're an established studio with experienced guys and have SMNC[1] under their belts (a great game but not sure what sort of financial success it had). Assumably they've been working on it since they finished SMNC as they have a fair chunk of art assets done. I expect the bulk of the production cost they've already got covered and the KS is just a pre-order mechanism and marketing exercise (I for example sent this link to 10 friends).
