Wall texture is "william_wall_01" by Christian "Duion" Femmer. Public domain license; found via OpenGameArt.org. Scaled down to 64x64 for Flagstone.
Flagstone's raycasting engine is largely constructed from the raycasting section of Lode's Computer Graphics Tutorial.
This game was created for the July 2014 edition of #onegameamonth. It's also the first game I made for #onegameamonth. Sorry for the bugs and/or lack of features.
The source code for Flagstone is available on GitHub.
Thanks for playing!
