Cool use of Mary Jane's Construct intro at the start... but the start page looked way too basic compared to the intro video. That looked off... I would make the start page look higher res.
Also, the game was too difficult. It was tough to steer the ship, the enemy fired just as fast or faster, and if you tried to maneuver (which was difficult) too far away you would be destroyed for not following the mission... even though you were never told what the mission was. The one way to probably beat the enemy relied on leaving the area, recharging shields, and then dashing back, firing, and repeating leaving the area (the enemy ship wouldn't follow you).
The program also crashed on me (only once) when I collided my ship into the enemy ship. Some error about "mutitexured sample..."
Edit: On idea to make the game more real... instead of automatically killing the player from leaving the game field... just use unlimited layouts/scrolling and use fuel. If the player leaves a certain area then you can drop his fuel.. once the fuel is depleted have some "scavenger ships" come in and blow you up. That is much better than having the ship randomly explode..
