I really like the idea, and I like the graphics. The ship feels hard to control though: the fact that you have to face what you want to shoot without any possibility to brake at the start forces you to put yourself in danger, and the inertia of the ship makes it hard to avoid said danger. The UI looks nice but is kinda hard to read as you have to always keep you eyes on the ship.
That said, it's a pretty impressive entry, which fits the theme well and could easily get expanded into a full game.
