OK, so here's the thing: I really can't bring myself to draw animals in pain, distress or neglected.
This is a fun lighthearted project and homage to games I loved growing up and still come back to =) I want to keep it that way.
However! I will add a donkey because I love this kind of positive feedback. Stay tuned.
Also the broken horseshoe idea is brilliant. Actually maybe I'll add a few other "misfortune" themed icons like in HoMM3.
Thanks!
