Yo this game is awesome. I'll first give a props to the aesthetics, It's so cute! I really love the packages inside the trunk jumping around as I create terror in the neighborhood with my abyssmal driving skills. I also like the detail of giving player slight clue on the package distance between the objective.
All things said, on the theme part I feel like more theme integrations should be added. Then the camera needs slightly more refinement a I personally think the view was slightly too low. But other than that, the simplicity of this game is definitely a very good hook that piques my interest.
Lastly, I want to talk about sound design. I really like the fact that the soundtrack portrays the game really accurate. It really sings "What could possibly go wrong in this morning package delivery shift?".
From visuals, system, sound, gameplay, and UI, if I could describe the entirety of this game in 1 word,
that would be : "Smooth".
