Out of curiousity, would it be possible to drop or race cubimals in the direction you're facing? It's totally minor and barely worth considering if the code is tricky, but I just thought it'd be cool to let them do that. That's all really.
What I love about them going in only one direction is that if you are standing in the lower right corner of the street and drop the cubi it will display a negative number distance that it went!
