Unfortunately it was really hard for me to play because the experience was really laggy (maybe around 5fps). You should take a look at optimizing your builds.
The sound effects and music was really cool. I also liked the button pressing animation (even if I didn't have a 60fps experience)
The idea has some potential. I liked it. It's hard for me to say what could've been done more in the hours, but overall, some more variation. Once I arrived at the restaurant to drop my guy off there was another one (I'm guessing that it's supposed to be someone else) He also wanted to go the restaurant. I was like, of course I'm going to drop you off, so I pressed the button for the restaurant and somehow the elevator still moved even though I was already at the right floor. That's some interesting elevator travel.
Overall, good job! It does take a while to make games in Unreal so congrats for finishing!
