From what I've seen of it, it captures the feeling of 1979 monochrome vector games beautifully.  I just have a hard time playing it because of the control layout.  The fire button is on the same hand as the movement buttons, and if while switching between two buttons you have both down at once, the control freezes.

Laser blast has some latency controls wise. If I want to give a single laser blast, I have to hold the down key for half a second. For an action game, this is undesirable. This game has a lot of potential, amazing aesthetics by the way. :)
