Hey! I've just put up for sale my newest tabletop game, Terra Incognita. It's a single-player game about building nightmare castles (or territories) with a deck of cards, and some pen and paper. It's built for use with my own Rhapsody of Blood, but it can make metroidvania-esque maps for your dungeon-crawler of choice - top-down or side-on, sprawling or tight, simple or a web of barriers and keys. You can find it at: https://ufo-jay.itch.io/terra-incognita
Here's a gif of one of my castles, in the process of being built:
