nice pixel art and retro sounds! I think it would have been even nicer with a parallax scrolling background. the premise to interpret incorrect signals in order to figure out the right answer is very interesting — unfortunately, it’s poorly communicated, and some of the solutions (that I read on the itch page because I got stuck on stage 3) seem overly convoluted. I think everything needs to be explained better, and maybe there should be more hints at how to figure it out.
