Hard as shit
But fun too! You definitely captured the style of an old-school arcade shooter, one that kicks your ass without mercy. The gameplay got a little too hectic at times, especially with some of the asteroids blending into the background, but it was still fun. At no point in time did I ever think of quitting because of the difficulty, though I did swear a lot.
The controls are good and the music is on point. The artwork is great too (reminds me of your old animation style where everything was very straight and lined with glow filters up the ass) and it was a great game to play. Good work. Make more shit.
