Took me a bit to realize I could have passengers on the left/right train cars, ha! Is there a penalty for leaving people at the station? I was also trying to figure out why I'd leave someone on the train past their stop?
The audio/music is amazing, such a catchy tune. As others have said, the subtle increase in the size of the passengers as you play is a nice touch. It'd be nice if the info appeared on hover, having to click on everyone to try and keep track of things is a bit tedious. Maybe each like/dislike could be a little icon in the future? Then that could also pop-up when scoring to reinforce the like/dislike factor.
Really fun entry! I made it to station 22 as well, is there a definitive end to reach or does it just keep going as long as you reach the quota?
