Yup! That's always been one of my downfalls when doing game jams, in addition to overscoping. As an artist, it's really hard not to want to do all the graphics super properly. I forced myself to use graphics from OpenGameArt.org just to focus on the mechanics, but even then I wanted to polish stuff up and do some things code-wise that would have eaten into my time. I was happy with just doing one piece of art though lol, a fuel depot for my game.
