I think this game hits well on innovative! I love the concept of this one. I love reading the London Underground tube maps, they have a strong nostalgia for me, so this game really hits a nice spot. I felt the writing on your Itch.io page also described your game well.
I had a bit of trouble understanding the timing needed for the game, and sometimes I'd board an unexpected train carriage. Perhaps next time it might be an idea to consider how to make the two green lines more distinct as well. It felt satisfying hitting the correct station, and I was left wishing that there were more levels/alternative map designs after reaching a certain amount of stations. Will you return to this idea after the game jam?
