Nice work. I like the art work in the subway section a lot! The second section is simpler, but that fits given what is happening. It's cool that you made it all in Japanese too! (Unfortunately, I have no Japanese language skills. Watching subbed anime doesn't count, haha...)
Speaking as someone with very limited game making time right now, I can appreciate mini story games like these!
I found one bug though... if you replay after completing a playthrough, the walking controls don't work anymore on the train.
