The game is pretty unique. it's very sad that the developer gave up on it. as for passing some of the hard challenges in the game there are some methods that you can change values like your money or life ... with the help of cheat engine. if you interested to use cheat engine there are many tutorials on how to use it and its fairly easy. even the program itself has some tutorial for how to using it. sorry for bad English my language is Persian.
- Save https://pastebin.com/GUhG4mbt as Captivity.CT

It may sometimes not work, in these cases, restart Captivity and try again.
If something is not clear, try googling it, there are a lot of tutorials for Cheat Engine.
