Super cute and great retro feel. It's a little punishing that if you miss anything they keep shooting at you from the side which is hard if not impossible to dodge. The level does get a bit busy and it can be hard to tell everything apart due to the one bit art. I think you did a great job with it but some color might be a big help to make things more identifiable. 

I really liked the art. I'm not sure if the size ratio was affected by my screen size but I often lost the ship in the field. I think maybe scaling the ship up and down when firing would help it stand out expecially once the page gets cluttered with enemies.  It was also a little hard to tell the difference between the background and the foreground because of the 1 bit colour.

fun play well done to make it 1 bit

biggest problem is the lack of bounds , making us yeet away from the screen
