"The ass?!"
I asked myself that every time I experienced the effect of a new drug, and always had a chuckle playing with the modifier. For a game that only has 1-button combat, it's actually a little deeper than you might expect. Being able to freaking JUGGLE doctors with your punches is tough to pull off, but it's just as satisfying as satisfying your Craving. Could definitely work for a mobile game to show to friends and see their shock with all the insane effects that take place with each drug.
You done good, Natpat. You done good.
