Oh my gosh ! I am tired !
Indeed, I tested with the purple girl (the witch if I'm not mistaken) and I di'nt see she had no animation. It seemed strange to me that there was an error regarding the quality of the work, but I did'nt think further !
It's official, I'm blind!
All my apologizes :)
PS. An animation of these two characters would be nice, but it's not vital. At best, I would do it myself in aseprite :)
