Whew, this one is fast-paced! Maybe too fast-paced, actually - I moved so quickly the tiles appeared to be moving backward, and couldn’t even read what I assume were distance markers of some kind. Most of the time that wasn’t a problem, though once the floor-mounted enemies started showing it up it made it tricky to actually hit them (I’d fly right past them…!).
In other ways, though, I think the pace could stand to be increased. Enemies didn’t show up that often, and those that did were quickly dispatched by just shooting backward consistently. Maybe there could also be some kind of “ammo” system, to discourage that strategy. I think the floor-mounted enemies could also be introduced a little earlier, since as-is there were a few minutes of very similar gameplay (which I found pretty easy) before things started to change and become more challenging.
Here was my final score, not sure if it’s good or bad:
