What a fun idea!
Only I was hoping for more of a "real" horse racing feel, but it's a great start!
I may be "off course" (pun intended), but my .0001 BTC's worth:
On first glance, suggestions:
a real track is circular, or rather, oval shaped
a bit longer race - to build up the momentum/anticipation
have horses that run, or moving legs at least
add real events to reflect real horse races, like falls, scratches, etc.
Hey thank you! i'm working on the graphics and so! my goal is to upgrade everything
