very nice proof of concept!
the idle style gameplay lends itself really well to the wild west theme; grinding manual labor in order to build a railroad fits the bill perfectly.
one note, some of the sounds are wayyy too much (the hunger warning, in particular). there was a moment in time where my food meter was constantly jumping between 0 and 1, and the bell sound became too much to the point where i had to take my headphones off to play the rest of the game
besides that one easily fixable complaint, really well done!
