A bootleg of Liquid soap (https://nifflas.lp1.nl/index.php?topic=7260.0), purporting to be the unreleased sequel "withheld from audiences by Nifforum of America due to its increased difficulty and unfairness." No company exists named Nifforum of America.
This "sequel" does not play like Liquid soap in any way and only superficially resembles it. It is also riddled with difficulty spikes and very annoying design.

Several other bootlegs of this nature are speculated to exist, including "Potatoes", "The Row", "A Climbing Apart", "Don't Pick Up the Lock", "Apollo Jones Ace Attorney", and "The Machine" (https://nifflas.lp1.nl/index.php?topic=7261).

I cheated and even cheating I still had to look in the editor to beat it but it was really something. Beautifully made and if you make levels it's incredibly inspirational.
