Adult PC Game: Night Shift v0.3 by GreyRaccoon Archive

You are a night shift caretaker of a Xenobiology Research and Expo Complex, the Xenoplex.
When there are no visitors and other staff around, you have to keep up the order, do the daily chores and attend to the needs of the alien visitors, the Polyflies, the Lassospiders and the Quasiworms. Everything looks to promise you a boring job, but as you get to know aliens better, you will find that not only can you change them, but they also can change you, in more ways than one.
