I’m at chapter 5 (of 7) and Steam is showing 15.6 hours (and 18/43 achievements if you are into achievements, which I am not.). I am still loving it.
I played a lot of it the last few days, so I am taking a little break to play something else. I need a few more restaurant days to make money to upgrade my suit to explore deeper to progress the main story quest. I blew all my cash training the best restaurant staff so that my kitchen is completely automated though.
