Thanks for playing :) And I did want to add some indicator on the active character at first, but it caused some problems - the NES can't display more than 8 sprites on a row, so when there were some sprites on the same line as the indicator, sometimes it (or the other sprite) would become invisible.
Later I found a way to circumvent this issue (when there is too many stuff on a single row, they will flicker because of that), but by then I was already used to recognizing the characters by name and there were other issues to fix... so I didn't put it back 😅
