Yup all elevators do that :( you have to stay clear. In Quake it would stop, hurt you a little bit then reverse. But I kind of ran out of bytes budget to do this kind of polish.I'll try to squeeze those improvements in the next version!
If bytes are an issue maybe you can just add a restart level button into the menu so you don't have to restart from the very beginning of the game?
From memory I got stuck in the roof while trying to travel down the elevator not upwards so reversing direction probably wouldn't help
