I did it! Twenty (plus one?) levels! I'm not sure who would want to live in these neighborhoods with houses packed so closely together.

After picking up the motorcycle the novelty quickly starts to wear off. Because you can't see your previous times once you move onto the next level and you don't get comparisons when replaying a level, there's not much inventive to try and get a new personal best. And since there is no failure state, the only objective is to be as fast as possible, so as the game is now there isn't the replayability factor which would exist with a score display.

Pretty impressive given that you used pygames. I've made a few game using pygames and it is much harder. delivered lots of letters!!

Congratulations on a successful jam.  It turned out well.
