Most everything you could ever want to hack can be parsed out and changed from the 6100 compressed line (145000+ when beautified) javascript file located in "USERPROFILE\AppData\Local\Google\Chrome\User Data\Default\Extensions\eopfmbpfhhfnklgmjpoehcjaajhpbhbl\1.0.0.11_0\game.canvas.js"
To avoid having to do this yourself I came up with some useful regular expressions to modify the file and threw them into an AutoIt script which I will upload shortly. The script automatically backs up your game.canvas.js but it cant be a bad idea to back it up yourself as well.
Edit: So apperently I couldnt actually upload it, but here is the source and you can run it yourself if you want to install AutoIt, http://pastebin.com/Jtu3V2EH.
List hacks and changable variables are at the top of the script.
