I recently finished the tutorial[0] as well, mostly to re-teach myself Python, and I'm planning to have a lot of fun rewriting it in C and Lua sometime next year. Roguelikes, both technically and as a genre, are probably right up HN's alley.

Also I'd recommend the subreddit[1] to anyone interested.
