Kenny Lee from Cellar Door Games gave a GDC talk yesterday in which he revealed that Rogue Legacy had earned back its development costs after one hour on sale, and shifted 100,000 copies in its first week.
The roguelike platformer cost $14,878 and took 18 months to finish, a big leap compared to Cellar Door's earlier Flash projects like Don't Shit Your Pants, Villainous, and I Have 1 Day.
"That's still a lot of money compared to the $1,000 for our previous projects, but if you consider the scope of the game I think we did a pretty good job at keeping the costs down," Lee said, as reported by Destructoid.
The company was founded in 2009 and is located in Toronto, Ontario. Rogue Legacy was released on June 27, 2013.
