I don't know if it's just me, but the mouse controls are incredibly choppy; if I move with even slightly more speed, the ship flies diagonally across the screen, beyond my control.
2/5 for the first game (the two points are for the initial concept).
1/5 for this sequel because you failed to correct this most fatal flaw that crippled the first game.
In a world of intrigue and fascination, with sheer beauty and a rich body of knowledge for us to gain, I sat at the computer and slaved away for the hard achievement to a flash game without break.
