Tried this one and must say this is superb and definitely feels like a complete game! Looking forward to seeing what other things you can pull off during the Trijam, especially if you end up trying to keep under the three hours.
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.
