Hello CryptRat, I also found this jam and hope I can fully participate because I heard that this is going to be a tough jam with all the rules we need to follow
Hello! If you're not familiar with first-person, grid-based dungeon crawlers then it's definitely worth taking a quick look at how some different popular ones play :
If your game is close enough to any game above you'll be fine, the mandatory features being walking in first person on a square grid and some sort of "life bar" and ""combat"".
Combat can take place on a separate layer from walking so it can be whatever and doesn't have to take place in first person or on a grid.
I agree.
They should be good resources on zooperdan's site although I never really dug into those : https://www.dungeoncrawlers.org/resources/gamedev/.
Heroine's Dusk is one where the sources are open and well documented : https://github.com/clintbellanger/heroine-dusk/tree/master/release.
