I noticed your post on Mastodon and bookmarked it to give this game a try. Built it from source on Linux Mint. Was immediately impressed and look forward to playing it further!
I donated a few gold pieces as a thank you for putting your time and effort into a real roguelike in the classic style, and coded in C, no less.
I may add some new features. Are you open to pull requests?
Anyway, nice work. This is great.
