I played the game through to the end. The bus was a bit hard to steer, so I jumped out and ran around until I found the passenger and knew where to drive. Pressing F teleported me back in the driver's seat! Because of the fast intro, I didn't know what the story was or who my passengers were. Inside the building it basically became a treasure hunt game. Luckily, I was not soft locked for finding items out of order, well done to you! When escaping the facility, I was told to find a passenger, but I found the ending of the game instead.
So, the atmosphere was recognizable, but I didn't understand the story. It's not really my type of game - I prefer puzzles to be solved instead of instructions to be followed - but it looks to me like you succeeded in making a treasure hunt in spooky surroundings.
