On floor thirty two the amount of money I currently had on my person exceeded the amount of money I had spent in total. After that, they never swapped back because I couldn't physically spend money fast enough to make a dent in the money I get per floor. I don't know how many floors there are here, but it is too many. The boss should probably be on floor 20, not 100 or whatever it is on currently.
Maybe there isn't one. It occurs to me the only reason I thought there was an end was the description.
