controls: space (to cheer on snail), mouse (to click things in the shop)
instructions in short: click the different parts of the train (cargo bin or cockpit) to go to them, cargo bin will have passengers you pick up
crank the wheel in the cockpit to go forward, events will happen and sometimes hurt your passengers and sometimes reward you.
ask anymore questions in my guestbook or just go to the itch.io page and download the manual
