Yeah the highlighting should be a solid color
A checkerboard over an 8 bit font is almost as bad as encrypting the text and trying to understand what it says
I think you should try to focus more on usability, how would a matrix overlay help people use it easier? lol
I'm still working on this feature. I was trying to reuse a tile from the font but I ended making a new one.
I'm using the background layer instead of the console for the highlight because it's faster to refresh in O3DS.
By the way, the matrix overlay is just an easter egg. I won't post more spoilers about useless things XD.
