Cool game! This is definitely a psychological horror game because there is nothing scarier than turning around and there's a ball right there. How does the scoring system work? I couldn't really figure that out.

For some reason the balls taking up the entire screen as they approach you is terrifying as hell 10/10 was on the edge of my seat the entire time. On my first playthrough I was scared of the balls and looked forward the entire time to prevent running into balls unknowingly, so I didn't actually notice the mechanic that if a white ball runs into your trail, they turn red and disappear. I think some sort of tooltip to point it out would be cool, but it could also be discovered organically, I might just not be so observant. The concept is pretty cool like some sort of reverse paper.io/Minecraft Spleef, and with some visual polish it could be fun as that kind of game!
