Awesome looking concept with different physics and mechanical opportunities. Reminds me of some shooters that question the idea of shooting like R-type and Sectis. Also the tethered double ship in Space Duel, or Thrust tethered to the pods.
I wonder how it controls if it is joystick or steer and thrust. .. With no shooting it could be viable as a driving controller game, rotary steering and button thrust. .. In case the developer is reading and doesn't already know and likes the idea : a completely unmodified Atari Driving controller can be directly compatible with a Vectrex game.
