Thanks again for checking this out and for sharing on Twitter. Lots of subtle changes due to Pico-8's lower resolution and square aspect ratio.
I tried to highlight a few small visual things that were personal touches here: the two layers of parallax scrolling on the stars that also clip with the foreground, the scanning beams, and the dithering/transparency on the shield.
There's so many little things that went into this. I'm just grateful that people think it's cool and are playing! :)
