I really like the way you made the character feel like they are on a train. The way they almost fall, the screen shake, the constant bumping into people, etc. I think the setting/mood was really well-executed, bonus points for that!
I think it's a little hard to understand the goal and how to achieve it/how to win. Maybe that's just me being dumb idk, it's pretty late here xD
But overall I like the concept and think if you polish it up a bit, it can be a really fun/funny game :)
