Very polished game. I think what you do well is the scope feels just right, and because of that, the gameplay is simple, but solid. The scope choice also allowed you to make sure there are few, if any, bugs, which is a big accomplishment. One point of feedback is that I beat the game without ever refusing passengers. I grabbed passengers, dropped them off, and then picked everybody up from where I dropped them, which was enough to win. Perhaps if the elevator capacity was decreased it would make the option more viable? I always make a point to give feedback, but even this is a tiny nitpick, so it won't have any bearing on my rating.
