It was pretty tough trying to make her look fancy enough with how tiny the resolution is. I also wanted to give her a bushy tail as well, but I ran out of the miniscule amount of sprite space available in Pico-8 to squeeze one in.
Working with GB Studio, I'm finding the thought process regularly comes back to "well if I duplicate these tiles here, it frees up extra tiles I can use over there", et cetera, et cetera 😵
