Beautiful artwork, and very creative idea! I had a little trouble getting any significant score and wasn't sure where I was going wrong, per se, but the proof of concept for this game is solid!
I found I wasted a lot of time going back and forth to check the order on animals - maybe it would be better to just have the order appear above each animal and stay there to reference visually instead of having to move the cursor?
Nice work, very lovely illustrations.
