## Description
Calibration Error is game about you and your best friend Emily. Hijinks ensue after an unlicensed, inadvisable experiment that leaves the main character in a body not quite normal. Will you manage to return to your male body? Or maybe you’ll end up having sex with anyone around you who breathes. The choice (as long as the choice is one I wrote in advance) is up to you!
