Speaking of the tram door sounds, why don't they play a little chime before they're about to close, so that people know when they're running out of time?

No, we should. And in elevators as well. I watched a video, and it was on intuitive design. It was about accessibility for people who are visually impaired, and how audio can assist people in the real world. And it was talking about elevators. So you know the bongs you get? If it's one bong, the elevator is going up, or two bongs...

Yeah, the other way.

So you can get in an elevator, not be able to see, and you'll know which way the elevator is traveling. That was awesome. So bringing those kinds of elements into the game would be great.
