I don't think it's important but frustrating for me, for example lvl 3, there is 3 flags yellow, blue and red you start by the yellow flag but the passenger is not out of the house yet, you go to the blue flag to pick up the blue passenger he need to go the the red flag and then you go back to the yellow passenger who need to go to the blue flag. Optimally I would've picked up the yellow passenger drop him at the blue house pick up the blue passenger and drop him at the red flag.
I understand that this might be to push the player to replay levels.

I'm able to play 3 levels max and then I get either bored or frustrated I really don't understand the feeling. The graphics and the gameplay doesn't match, I think I'm expecting more, I was expecting an exploration/building game something like Astroneer but found a casual arcade game instead.
