I like the looks/lighting, I've never played Gyruss but I do have a feeling the controls make more sense with a joystick. I found it worked fine if I pushed the arrow keys as if I was following the ship which might feel more intuitive with a joystick than a keyboard. In general I'm terrible at any tube shooter, so I have little experience to compare to other similar style games.

Thanks for the comments and for your insight. The controls are really made for an old style 8-direction joystick, and works much smoother with one. That said, I think it is pretty easy to learn using the keys and also (in this case) part of the challenge for me to re-create the classic controls. In hindsight I should have added an option to have alternative controls.
