I wanted to just recommend a step by step tutorial for creating a traditional roguelike that I truly believe anyone with a computer and a tiny bit of interest in game development can get started with their creation for this game jam. I'm simply recommending it because it has helped me out a lot with getting into the genre.
Check out the Broughlike Tutorial by Jeremiah Reid: https://nluqo.github.io/broughlike-tutorial/index.html
You can play the finished game here: https://nluqo.github.io/broughlike-tutorial/completed/stage8/index.html
Anyone with a computer, text editor, and basic image editor can create a completely finished traditional roguelike from scratch with no dependencies, libraries, or other tools.
Best of luck to everyone in the game jam!
