To echo the last reviewer, I wish I was good at implementing chain mechanics. While not 100% novel each implementation feels like it. This was an optimal use of theme and special object, in turning the tables on that pesky RNG. Too much repetitive timing challenges for my tastes and abilities, but I'm proud to have tried the whistle, which was fun. That check point where I had to first use the whistle, I felt like Sisyphus as I kept falling off the staging island.
