Glad you guys liked it.
I'll likely be posting further examples and updates occasionally in this thread, as I continue my work on making a roguelike game.
My next steps will probably be to make a Dungeon class to contain the levels, with a way to connect the levels to each other, and getting a character moving around within it. Not very difficult stuff, but my time is more limited than I'd like these days. Things like filling the dungeon with random stuff and creatures will follow, here.
I'll also likely be cross-posting this project across different threads later, as I get to field-of-vision and line-of-sight examples, and other different topics that will crop up with it.
