Seems like a neat game but I couldn't play it. I can't tell where I'm going or how fast because the stars in the background don't move, so there is no way to sense the movement of the ship.
No animations. No boundries on the play field. Bullets travel slower than enemies. Repetitive and bland gameplay. Player moves too slowly. But otherwise it was an ok game.
I liked this game better when it was called Double-Wires, it had a stick figure for a main character and it was all in Japanese (i.e. this game is a ripoff of another game)
