The thing about html based games is that, if you are playing in chrome, you can use the console to change the various stats like money, time, etc.
So either this game doesn't support the console( which i seriously doubt, given the ui is pretty similar to other console supporting games) or NO ONE here knows about it, which is quite shocking!!
To access the console, in any twine based games( works on google chrome, not sure about mozilla and others):
1) Press F12 to open a new side window in your current game window.
2) Select console from the top selection bar (you'll see options like elements, console, sources, etc. Select console).
3) Type : SugarCube.State.Variables
4) Press enter
5) And there you have it!
All the variables being used will be listed in front of you. Make changes as and how yous see fit PROVIDED YOU UNDERSTAND WHAT YOU'RE DOING!!
Personally recommend to create a save before doing any such stuff. press F12 to close the console again. The best part about this is that you DO NOT need to have a cheat version of the game.
PS: just tried it, works just fine!
