Ok I started playing Cat Quest series and I was able to at least get one hack on cheat engine for the current version of Cat Quest. you can give yourself gold. not infinite but just add the amount you want and kill at least one mob after applying the value change. I've tested it for the last hour or so. It should work for the Epic Games version of the Cat Quest. Enjoy and let me know if it doesn't work.
