SciGirl: The internship is a 2D action-adventure platformer game that follows Sonia, an intern in a science laboratory, and her mentor professor Ivan. Together, they are working on stabilizing a chemical that was invented by the professor with which you can shrink or enlarge living organisms. Sonia will be looking for the professor, who disappeared because of a mistake he made after doing several tests where he accidentally used the chemical on himself while he was testing his suit and he got stuck somewhere in the lab but in a shrunken form. Sonia uses his notes to recreate the chemical as well as additional doses for bringing him back to normal size.
