I'm sorry to hear that. But cheat is possible and I have mentioned several time on how to. You basically can edit the save file to have as much money as possible or much affection as possible. Save file is easy to read.
Regarding crashing, this was an issue on earlier versions and was fixed on latest. I'm working on bugfixes and other improvements regularly. Next update will be on tomorrow which contains more fixes and features like partially undressing.
But anyway, thanks for trying the game. :)
