This was an interesting game. It's a great concept for a typing game. It gets pretty intense near the end, and you really have to strategize on top of typing quickly. I thought that everything felt really polished and the gameplay felt satisfying.
One issue I had, though, was that sometimes I couldn't read the names of streets because the vehicles or text were partially obscuring them, making me have to guess, which cost me valuable time. Maybe you could find a way to make the street names next to the active unit more prominent? Maybe make them appear on top of everything else somehow?
