Calibration Error

Calibration Error is a comedy/sci fi/smut story of science gone wrong. Hijinks ensue after an unlicensed, inadvisable experiment that leaves the main character in a body not quite normal. Is your friend Emily, the inventor of the machine, really trying her hardest to fix it? Will you manage to return to normal? 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!

Surprisingly it is not that bad but actually rather good. Screenshots with white background supposedly from earlier versions. Game is not that long, have a nice story with branching and not forcing into any gay shit.
