This game is hilarious (some music might be a nice addition). It reminds me of that game about a bear driving a car around to fatten up for the winter where you only controlled one arm.
This is really hard, though. It's tough enough just reversing after a crash since the gear selector springs back, but then the flies come to take your delivery. ha ha!
Edit: I just realized this is intended to be multiplayer. That would be much more fun.
