I could never get past the first stage because I could never time it properly, and sometimes it was latent. I also didn't like only having up/down as options, that's kind of an uncomfortable position for my hands. Maybe left/right could also work? Or left/down? I also think it should give you a random property, instead of red every single time to start with, variation would make it more fun and less robotic. I loved the art! Good job!
