Best way to cheat is editing the save file.
Go here on windows C:\Users\"YOUR NAME"\AppData\LocalLow\TheArchitect\Lust is Stranger
There will be a folder called "saves" and inside that will be folders for each save file, as well as a preview image that will help you confirm you're looking at the right save file. All you need to do is find the folder number that matches the in-game save number you want to edit, open it up, and then edit the
state.xml file in that folder. Editing an xml can be done with the basic notepad app that comes with your computer.
Once you're in the save file, search ITEM:MONEY" state="
The number after "state" determines how much money you have in-game. You can just set it to something like 30 and never have to worry about money for the rest of your playthrough, if you want. Save the xml, go back into the game, load your file, and you'll see your character has the amount of money you set it to.
PLAYER:STAT
ARAGON" state="
PLAYER:STAT:RENEGADE" state="
Same as above. Energy as you described. I recommend experimenting. Make a copy of the file and try it yourself.
