There are many different trains you could take - which one will you take?

Controls:

Space - continue

W or up arrow - go up

S or down arrow - go down

Mouse - you can also control the game using the left mouse button if that's more your speed.

Escape - you can press escape any time you make a choice to remove all UI. Makes for a good screensaver. You'll have to reload the page to get the UI back.
