The game is currently in "pre-alpha" and, on Xbox 360, is looking like a PS2-era shooter with more current anti-aliasing applied.
Literally, all that is needed to proceed is the left thumb steering the on-screen character and the right index finger, locked down on the designated shooting button -- just keep on holding it and the game will automatically target a new enemy once the current one has absorbed too many laser blasts and disappears into the well known in-game ether.
