Use mouse for everything. This also means the game is mobile friendly. Link to part 3: https://scratch.mit.edu/projects/372878792/ Keep in mind that I released all these parts at once.

@Flyoli did the buildings in the scrolling. Newgrounds had the music. Notes: I was going to make an animation of you and Gobo getting on the train, but scripts weren't working. I was also going to have a puzzle on the train, but the scripts there didn't work either.
