For your gaming pleasure is my entry in the 7DRL challenge: MythosRL, a game of Lovecraftian Horror.
Unfortunately I ran out of time before I could implement magic, sanity, and some other classic Lovecraftian tropes, but the game is a functional dungeon crawl.
The game is implemented in Java. UI elements and rudimentary functionality was implemented by Yours Truly before the challenge began.
