GAMEPLAY: You say it's a test, and personally, I do think the concept holds up well. Not many games explore the physicality behind controls like this does. It definitely needs some fine-tuning to stop being frustrating, though. The ship is as big as it needs to be for visual clarity, and the movement speed inside of it is both precise and reactive, but the environment is far too cluttered and fast-paced to make navigation possible. I did not understand how shooting works in the time given, and even if I did, it seems too slow to be useful. Pure navigation may be the better call. A score would also be a nice touch, and 'time alive' is a simple one to add.
VISUALS: Nothing too inventive with the shapes given, but clear and serviceable. The fire behind the meteors was a nice touch.
AUDIO: No music, sad. The sound effects are retro where perhaps sci-fi would fit better, but not bad.
THEME: Putting the theme as the title is pretty cheesy, maaan. It's a toss-up: you're literally limited inside the ship, but the ship can go anywhere it pleases.
