Taking the challenge of minimal worldbuilding to heart, I'm building a TTRPG in 2 parts: squire and knight. There's basic mechanics for making skill checks and leveling but that's about it. It's currently ~530 words. Debating if it needs a combat system, but I might have to rework a lot of stuff and end up doubling the word count if I do that.
I don't think I'll be able to playtest it before the jam ends, but if people would like to take a look at the draft and provide feedback it might help!
