Thanks for playing! Yeah, sleep deprived me was struggling to get the background to move correctly -- I needed to spend more time improving the game-play.
I was able to tell myself that when the game starts the trolleys are moving with the player but slower, and that when the trolleys sped up and started moving faster than the tracks that all the conductors decided to spontaneously shift into reverse. Lol, not the best explanation on my part, but it made sense at the time.
I'm glad you liked the coin system -- we decided to add them because the game-play was rather dull at first. I appreciate your feedback! :)
