Back in Time =============================================
Episode 2: Conducting an Experiment
=============================================
The teleporter led to a science lab. You had travelled back in time to when the platformer creator was still in beta mode. You couldn't re-enter the teleporter to go back home, so you had to build one, but you didn't have the materials! The genetically modified creatures had the materials, so you had to kill them. After you killed them, you conducted the orange teleporter experiment.
