Thanks for trying my game!
My initial idea was to fix the beat to 60 BPM, but I run every concept I have through a cheat test, asking what would trivialize the game. Having a wall clock or a metronome would definitely solve it instantly. That's why I moved from a fixed beat to a randomized one every run, and 8 ticks aren't enough to capture & sync to the right timing, while it's still close to the original 1/sec rhythm that we got internalized since we were kids and learned to read the clock. :)
