I really like the concept, it fits really well with the theme! Though I'm not sure I understood completely the mechanics, are the vehicle spawned randomly, or is there a logic to the spawning ?
Thanks for your comment!
At first we wanted to add deterministic random spawning, to ensure the levels could be repeated expecting same results by using a seed. But in the end vehicles and people spawn every couple of seconds (with a small random variation). That made it a lot more rng based.
