The Blue Imposter is a space action game, where you have to play as a blue imposter in order to survive and escape from a space station inhabited by aliens of other colors, and kill all the other crew members in order to be the only survivor.

The game starts with the imposter having escaped from a space station towards other planets in the solar system. On your way, you will be attacked by other crew members, and will have to kill them in order to survive. 

There are two buttons for the imposter to use: one to jump, and another to perform an action.
