I played your game and the amount of horses is absurd, but i do think you tempered with the counter a bit, if I click outside of the racetrack one horse spawns but the counter says that over one thousand spawned also turn the volume down please. It is incredible how you made it without lag being a big issue.

Thanks for the valuable feedback, thanks for playing! I'm so excited to hear that someone tried it! The one horse spawning is a floating horse spawning. I added those for the extra layer and to show off the use of flow fields to control them. But if you look at the "track" it also spawns 1000+ horses although they start to stack after a while they are still being simulated. I made the spawning increase exponentially just to reduce the time it takes to get to a million because I didn't want the player to lose interest. Thanks again!
