First off, the graphics and sound were great, and the aesthetic was very nice. The minimap was also very appreciated.
I would have fixed the camera's rotation because the rotation was kind of disorientating.
There was a bit of confusion because it seemed like I had to juggle a lot. I think that maybe cutting out some of the mechanics to highlight others would have been a good choice. So maybe I could just have unlimited pizza to not worry about running out. It was also confusing exactly who I was delivering to at times. Maybe if they could have an arrow over their head?
All in all though impressive entry. Could use a bit more of a focus but it did have a good GTA/Crazy Taxi feel like you were going for.
Nice one!
Oh and like others said, the map was pretty big. You'd be surprised that sometimes a smaller map actually makes the game feel better. Seems counter intuitive but I read it in a Sid Mier book!
