This is a great interpretation of the theme! Super clean gameplay. I enjoyed the way the thruster did not provide finite Y control, but slowly drifted back. This is the kind of 'not in full control' feel I really enjoy (similar to driving a car off-road). Considering the tight loop, the only thing I would have liked is a reason to release the blaster. As it is, the button may as well be weighted down.
Fun entry and I'd be interested to see where it goes next, if you add more to it!
