Stellar, as always.
I could nit-pick at minor things that irritate me (such as not being able to poison yourself with the dissolver for good measure), but they add to the experience via characterization. Other than that, this game had everything it could ever need, and a Markiplier reference! I can't imagine how a game so short could be any better.
As for the players out there, just remember...DON'T ESCAPE.
