I've been doing Game Jams off and on for a couple of years, and while I've always had a lot of fun, and some great ideas (I still work on them, now and then)... this was the first time I actually got to the point I felt like I could actually click "publish" on before the deadline. Some of that is definitely not having to do the art myself - in fact, it helped speed along the design by just giving me a catalog of assets to thumb through and say "I like this, let's see what I can do with it." But also, some of that was just slowly learning to flesh out ideas before rushing into them, and to have a "minimum viable product" in mind, to keep from over-promising and under-delivering.
All in all, it was great fun and I hope to see more in the future!
