The team behind Cellar Door Games has released the source code for their popular Roguelite indie hit «Rogue Legacy», which came out 10 years ago. Note that this is not an open source project, the source code is released under a non-certified OSI license, and the release does not include assets from the game. However, this allows the community to continue developing the game, as well as giving the developers a behind-the-scenes look at a successful game made in C#/XNA/FNA/MonoGame.
The source code for «Rogue Legacy 1» is now available for everyone to enjoy. If you enjoyed «Rogue Legacy» and enjoy programming in C#, please check it out here.
