Gotcha, ok! The fact that the game is unfinished and that there is going to be a public SRD wasn't stated at all; the description would greatly benefit from mentioning that.
To address your other points. With these kind of jams, I've always seen an easily accessible document that I can download right on the jam page, and sifting through blog posts to put the game together piece by piece isn't something I'm a fan of. The blog posts are also missing a lot of information that I would find crucial for creating something for this jam. As for the server, I don't like joining a jam's server until I know for certain I'm going to participate; that prevents my server list from getting clogged up. It's really nothing against you or your community. And how can I play the game if it costs money to purchase?
Finally, I'm also not appreciative of your sentence at the end of your message; it's a rude tone to end on. Everything you said was fine up until that point.
I apologize if I came across as blunt with my initial message; I wrote it more negatively than I intended it to come across, and I'm going to see if I can edit the title (editing the post at this point feels insincere though, as I can't take back how the content made you feel). I am not trying to disrespect you or your community. I love making content for games in these kind of jams, and I like the premise of this jam a lot. But it doesn't come across well when, in a public jam for community content, the only link to the full game is to a purchase page.
Good luck, and I hope that SRD comes out smoothly.
Edit: Apparently you cannot edit a post's title. My apologies.
