I had a ton of fun playing with this! I decided to make wolves instead of horses (since wolves are my favourite animal), screenshot of a race i did attached (the blue wolf was my set's jovial merriment, and grey was my set's cyan, basically LOL). The quadruped run cycle i drew (sorry, typo, not coded) for them still worked SUPER well even though the animations are likely built for bipeds so that was neat to see!
On that note, is there any plans to be able to customize the victory images and the winning item (i.e switching the carrot for something else), or are those hard-baked into the game and unable to be customized like the horses and levels can?
