DISCLAIMER: I take no credit for this, I found the source code on the internet, compiled it, made a few changes and included the 1.1.4 Puzzles file, the new one was broken horribly, resulting in numerous un-playable levels. All credit goes to Adam Betts and Lucas Newman for creating this (and a little to me, for fixing the code a bit to have no warnings and run better on 2.0). Personally, I couldn't live without my Lights Off.
