Good, but not the best
The game is fun in the beginning, only two guys waiting, esay. But suddenly everyone calls the elevator almost at the same time, then you can't reach them because stopping the damn elevator is very hard and you lose the game!
I've seen some great games made by you, but this one wasn't very good. There are lots of thing to improve on.
Make the elevator stop easily. Most of the times that I lost the game was because I couldn't stop the elevator.
Make different levels difficulty. Make an easier one that takes more than only 3 people to lose the game. Also, make less floors. 30 is a lot of floors.
And since when elevators bounce when they hit the ground? I've never seen it before.
The game has a good idea, but it wasn't very well executed.
