The concept is very creative! The animations look great, and I liked all the different floors. As a sound guy, I also appreciate the sound design, especially the use of FMOD to make the elevator engine sound, really cool.
I do think the gameplay would benefit from a bit more clarity. I sometimes couldn't tell which floor I was on or whether the elevator was close enough to a floor to open the door. Maybe having a very visible line on both the elevator door and each floor would make it clearer when they're properly aligned?
Still, very nice submission. Congrats to the team!
