I'm glad you enjoyed it so much! I can't really take credit for the coding as I only made the sounds, but from what I've heard it was really exhausting to implement the enemy AI to actually listen to the sounds, so a full release is going to have to wait a while (if it ever happens). The elevator is called with "e" and you had to go up/down with "W" or "A" respectively. We have also added the controls onto the page now.
