The difficulty is high (I only managed to get 2km) but it's definitely just as fun regardless. I love the concept of you being God, desperately trying to move cars away from Bob. I started frantically moving cars that weren't anywhere near him, just in case he randomly swerved!
It's a shame you weren't happy for how this game came out. Considering this is your first jam, the fact that you managed to make something that was fun, fun-ctional and bug free is great (I certainly wasn't as lucky when I started doing game jams and I was in a TEAM). Try and see what you can improve after the jam. Practice your art and music skills. I think you'll be very surprised with what useful stuff you can pick up in a short amount of time.
Goody entry. Hope you do well :)
