Experimental indie game Dear Esther is profitable - less than six hours after going on sale.
It sold over 16,000 units during its first day on sale (yesterday), its creators announced this afternoon.
thechineseroom and Robert Briscoe's Ł6.99 first-person ghost story paid off its financial backing from Indie Fund in just under five and a half hours after strong sales on Valve digital download platform Steam.
Dear Esther was originally released in 2008 as a mod for Half-Life 2 developed as part of a research project at the University of Portsmouth.
In 2009 Briscoe, a former environment artist on Mirror's Edge, took the project on, overhauling the visuals and level design for release as a commercial game.
