In Golden Krone Hotel you take advantage of the differing abilities of your vampire and human forms, including their interaction with dynamic light. This one eventually turned into a bigger commercial roguelike and has done pretty well on Steam since releasing a year ago.
Like most game libraries, libtcod handles basic features like your game window, mouse and keyboard support, bitmap fonts, and palette and color manipulation. But it also does a lot of the roguelike-specific heavy lifting, like map generation, FOV, and pathfinding.
Ultima Ratio Regum and Temple of Torment, two roguelikes I showed earlier, both started with the game they created using this tutorial, and eventually grew into their own things. libtcod is pretty great, and has been receiving updates for ten years now.
There are quite a few articles (that list there is just the general table of contents!). Although a lot of the content is older, most of the articles are just as relevant today. This is actually where I got started years ago, and found the articles both inspiring and enlightening. (Also a little scary at first, but remember, roguelikes are developed piecemeal--take it one step at a time!)
For some people tilesets have the advantage of sparking your imagination, if you need that to help with development. That said, you may have seen some of these tiles in other roguelikes before, and that can be one of the drawbacks (the visual style not necessarily being uniquely associated with your project), but good-looking free/inexpensive art is invaluable for indie devs.
Roguelikes are generally based on good/interesting gameplay, but having a unique theme not only makes the entire experience unique, it also gives you a source from which to readily draw brand new mechanics. (A unique theme almost forces you to take this route.) In particular, historical and mythological themes offer a huge range of established material to explore and expand upon. People also always seem to want more sci-fi roguelikes than what we already have, a relatively underexplored group of themes compared to how broad it is, and how much sci-fi content we see out there in other genres and mediums.
Today DoomRL developer Kornel Kisielewicz is busy working on the DoomRL successor Jupiter Hell, a prime example of using an XRL to grow a large fan base, and then relying on them to support an even larger commercial roguelike.
Even my own first semi-roguelike project, XCOMRL, belongs in this category. Based on the original UFO Defense, it started from an IP with mechanics I was already really familiar with and love, which helped a lot.
Many updates are planned during Season 2 including new relics, new weapons, new Toy Workers and more. We hope to continue to hear from the players and make Anvil a solid top-down roguelike shooter that players can enjoy!
