Innovatively perverted gameplay with excellent execution! The kinks are integrated directly into the gameplay! Puzzles and action are original and fit the themes in really good ways. The controls and physics can use tiny bit of precision tuning, but feel really great already. Alternatively, just having fewer demanding jumps and around 30% less item requirements would make the controls feel perfect as they are for me. The mouse and keyboard combination is a really good choice and lets you adjust things as you're moving. I also enjoyed the non-intrusive and well-paced tutorial.
Sound is the biggest missing element at the moment, a well-picked soundtrack and subtle squishy noises would really seal the deal.
The art is very good with varied and smooth animations. I'm also a big fan of the mostly grey color scheme that makes the characters pop out. Very nice UI design.
You are charting some provocative and previously unexplored territory with this project. I am excited to see what else you decide to do with it!
