I just learned how to parry but I can't go back down the stairs to go back on the train. Pls help.

To do this, just hold down and press jump on the platform that leads to the stairs, i'll send a picture to show where to do it... when i get up to that point again, my save data was deleted.

Yep, on any platform you can hold down and press jump. The train station is still kinda unfinished, it's got that white awning that looks like a big sail.
