This town needs some more firefighters to help out! Clever take on the theme and limitation. It was a nice shift from a lot of the other jam games I've played so far. The art was simple, but effective and charming.
I think it would play better with a single action button, so the same button to pick up civilians as it is to drop them off, or as was suggested, he should autodrop them when you're in the ambulance zone.
Overall, really well done!
