I never really liked how to fix exploits, had to set goals on parts midway through the chain of events. Robbed ingenuity most of the time. Maybe it was due to a deadline and had no way to fix/rework.

About the original "How Does It Work?":

The puzzle was one of the weaker puzzles in the Expert category. It was very easily cheesed: the original left the lava lamp (now a whistle) untied, and gave you a spare bucket (meant to be a red herring), meaning it could be lit immediately. The additional objective of turning on the fan (removed in this version) was trivial at that point. I had to lock some parts to prevent this. The actual puzzle itself wasn't too difficult after my changes, so it is now Medium difficulty instead.
