Is it okay to use the Unreal engine blueprint system?
We actually held a poll on which weekends would be best for our community as we know some people celebrate 4th of July weekend, and some don't, and our final result came down to July 17th as our weekend to hold the Jam. But I can redirect you to other Game Jams that are starting soon, as they're all listed here: https://itch.io/jams
I believe they aren't in the same time. Even if it was, I would need to wait for the assets to be made by an artist that I am collaborating with, so I will have plenty amount of time making a game for No Code jam. I have an unfinished project, but it would take a long time to make since it uses pathfinding which is pretty hard to do in a Drag and Drop engine.
I can try remaking a tycoon game that I made a long time ago, just to see how I improved in over these past 3 years or so.
