Be the first to review Jef
You wake up as an alien from Karzalinx, not knowing what your name is or how you got there. Soon you discover that your planet has been taken over by a giant evil spa cult. You have to find a way to escape through a space-time ganglion that can take you to various alien colonies throughout the universe. Your goal is to get to Earth where aliens are attempting to right the wrongs of humans by doing things such as forcing former billionaires to put together Ikea furniture for regular people. Among all the confusion of a recently colonized planet you hear of a kidnapped scientist who can help you find out what your name stands for.
