I'm in a similar situation. I've got a lot of words, but no game. I wound up redoing part of it because the attack values were increasing too quickly relative to the life points. And the weapons weren't even included. It's a mess.
I did a playtest with my weekly group that I normally GM Numenera for. The flavour was on-point but the balance is off. I don't think I can get that perfect in this revision. I'm labeling it "Playtest Edition v0.1". :)
Getting something ready enough to playtest from is already an achievement on itself. My entry to this game jam most likely will also be a document that I can playtest from. There’s nothing stopping us from developing it further in the future, and playtest is always useful.
