It is a SugraCube/Twine HTML game, use the browser console. I use FireFox and just press F12, and click the Console tab.
Type in:
SugarCube.State.active.variables
and hit enter. Find the ... at the end of displayed line and drop it open. Those are the stored variables for the game.
To give yourself money in this game, the variable is 'cash'
So type in
SugarCube.State.active.variables.cash=100000
and give yourself a total of $100,000 or whatever amount you want. Don't make it too much or it kinda defeats this being a Management game... It does not add that amount to the cash - it makes the 'cash' the amount you type in.
Hope that helps!
I found that once past the first few weeks, with the viewing booths and such and working the girl, cash builds up nicely on it's own.
