For those who enjoy SPD I recommend checking out some other popular roguelikes, many of them are also open source.
Some of my personal recommendations would be brogue (probably the most beginner friendly), DCSS (friendly, tons of content), ADoM and Cataclysm DDA (a sandbox survival roguelike, quite a unique mix)
