I seem to have accidentally stumbled upon the Developer Console while I was mashing buttons after getting stuck on a bug.

While playing the game, type: 1 2 3 4 D for the console to drop down. This allows you to give yourself unlimited funds by clicking on 'gold', alter the genes/stats of your horses, and other options. It can be toggled by pressing D again. It really is that simple.

Sorry to the developers if this wasn't supposed to be found, but it wasn't exactly hidden well...

Remember: With great power comes great responsibility. Don't abuse this gift beyond your own enjoyment.
