It looks like a bad copy of is this seat taken. Not a bad idea though. It is good that you gave a try, so you can learn how hard is to make a game. Here some constructive points:
1- Side view does not improve the gameplay.
2- There is no time enough to arrange all passengers acording to the constraints. In these kind of puzzle game, pace is important. Just letting the user click on the close door button rather than be time base will improve the UX.
3- When hovering on a character, several are highligthed, I never know which one I will pick up.
4- it is hard to get the visual feedback of noise vs no noise person. Being all together does not allow you to recognize who is who.
5- No idea why there is no feedback about how many stations a passenger will ride. You may want to compute how many points you can get / loose if you put him/her in the right place.
