Oh thank you for the kind words! And I like your ideas quite a lot, I hadn't thought of them, mainly because of trying to keep the scope as small as possible for the game jam. Yet you can see that I didn't fully deliver a complete experience either, so that is something I will work on to give the game a small update. You can also see that I had planned out an unused UI element (it's the gray empty box in the bottom right corner) that I planned to display customer's detailed info when you select them, but sadly that also got cut.
But you made me kinda curious haha, what other elevator operating simulator games you have played before?
