Choke on my Groundhog, You Bastard Robots

Choke on my Groundhog, You Bastard Robots is twin-stick shoot 'em up. Each time you die, your previous playthrough returns as a copy to assist you. The number of ghost allies increases with each new life making the player stronger with each death. Robots are always bastards. There’s no way around it. We build them and they killed us all. Well almost all, I’m the Earth’s last survivor. But with my time traveling groundhog sidekick I’m going to destroy the robot liberation army and take back Earth.
